EXPERIMENTAL AND NUMERICAL ANALYSIS OF AN AUTOMOBILE CABIN THERMAL MANAGEMENT...IRJET Journal
This document presents a numerical analysis of using phase change material (PCM) to manage the thermal environment inside an automobile cabin. The study models an automobile cabin using computational fluid dynamics software. It simulates the cabin temperature over time under two conditions: with and without a PCM-incorporated roof. The PCM used is calcium chloride hexahydrate, which has a melting point around 24-27°C. Both steady-state and transient analyses show that incorporating the PCM into the roof helps maintain cabin temperatures around 0.5°C cooler on average compared to without PCM under direct sunlight. The PCM absorbs excess heat to prevent temperature inside from rising too high.

Abstract: The conventional vehicle suspension dissipates the mechanical energy i.e. potential and kinetic energy. In spring potential energy is stored and kinetic energy is wasted. The aim of paper is this wasted energy is compressed by using single acting cylinder by proper arrangement. The main aim of this paper is the compressed air production using vehicle suspension is given to the air conditioning system. The pushing power is converted into compressed air energy by proper arrangement .The pneumatic single acting cylinder is used for this project to compress the air. The output air from the pneumatic cylinder is collected through quick exhaust valve and non return valve and this compressed air stored inside the storage tank. After this research we concluded in car there is a lot of fuel burn only for working of A.C. while driving the car. If A.C. will run on other system rather than fuel then there is lot of fuel save in car hence the efficiency of car will also increases.
CFD Analysis Of Straight Ventilated Disc BrakeIJERA Editor
Brakes are the key pieces of a vehicle that plays an active role in safety and performance of the system. The
study of aerodynamic cooling of a disc brake in real working condition of vehicle is important in present
situations. Brake discs get very hot quickly, so it should be dissipated properly through different modes of heat
transfer. Contributions of these heat transfer modes are different in different type of problems. The cooling
transfer rates are different in vane surface and frictional surface of a disc brake. Also the temperature varies in
each small interval of braking time. So a transient problem simulation is important to study the cooling of a disc

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.

Abstract
It takes times for an air-conditioner to effectively start cooling the passenger compartment in the car. So the
passenger of the car will feel the heat in the car extremely before the air-conditioner fully cooling the interior of
the car. Excessive heat can also damage an automobile's interior as well as personal property kept in the
passenger compartment. So, a system to reduce this excessive heat by pumping out hot air and allowing cooler
ambient air to enter the car by means of two micro fans was made. Also a cooling chamber was set up around
the inlet fan to cool it a little further.
Keywords – Air conditioner, Cooling Chamber, Micro fans, Solar panel.
I. INTRODUCTION
A device was fabricated that controls the
heat development rate in parked cars with the help
of solar energy powering. The working of this
device is based on Newton’s law of cooling. A study
is conducted to measure the temperature inside of
the cars that all directly exposed to the sun, with no
major shadows on any of them and activities to
choose the suitable apparatus that will be used to
develop a device for dissipating heat from a car..
System consists of two micro high efficiency fans
for circulation of air into and out of the parked cars.
One fan is for inlet and the other for outlet actions
respectively. The inlet air forced in by the micro fan
is passed through a closed chamber containing a
coolant. The coolant primarily used is liquid
acetone. The electric power required for the
functioning of the two micro fans are harnessed by
solar panels by solar energy harnessing principle
This paper deals with to design a device for
heat removal inside a car which will help to cooling
down the temperature in the car and reduce the
excessive heat felt by the passenger of the car on
vehicle start-up, besides reduce the damage an
automobile's interior as well as personal property
kept in the passenger compartment.
II. LITERATURE SURVEY
The main reference that has been utilized
for doing this paper is the journal of “How is
Interior of Car Parked under Sun Much Hotter than
Atmosphere? “by Jonathan and Grabianowski It can
be said that our project is a simplified and cost
efficient model of the prototype in the journal. The
next reference is Lange's Handbook of Chemistry
that provided us with relevant information about the
coolant that can be used in our project.
Figure 1 Heat effect on cars
On a typical summer day, the temperature
inside a parked car can be as much as 30-40 degrees
hotter than the outside temperature, ie. on a 30-
degree day the temperature inside the car could be as
high as 70 degrees. Seventy five percent of
temperature rise occurs within five minutes of
closing the car and leaving it, ie. On a 36 degree day
the car will have reached 55 degrees, within five
minutes. Ninety percent of the temperature rise
occurs within 15 minutes.

in the inlet side. the inlet atmospheric air fed to the
device is passed through a cooling chamber
consisting of liquid acetone .the cooled air is
circulated in the car cabin due to inlet fan force and
the warm cabin air is pushed out through the outlet
of the device .the primary source of power for the
operation is harnessed from solar panel
IV. DESIGN SPECIFICATIONS
The frame being the most important part of
the system had to be designed first. We first made a
model of the frame and tested it on a car. Finally, we

had to improve our design. Designing of the frame
was mainly done on AutoCAD. The final frame
structure was fabricated with 2mm thick iron sheet
by gas welding operation.
The frame was designed in such a way that
the inlet side can hold a coolant chamber which has
the shape of the English alphabet “U”. The bottom
of the coolant chamber is 2cm thick and the sides
being 1cm each.
SPECIFICATIONS OF FRAME
Frame material : Iron sheets 2mm
thick
Length : 16.8 cm
Breadth : 13 cm
Height : 8.4 cm
Inlet Area : 6.4 x 3.5 cm2
Outlet Area : 8.4 x 3.5 cm2
The other components used were 280mm
square CPU micro fans for inlet and outlet. As the
coolant Acetone, which has boiling point at 56.2°C
was used in the acetone chamber which was a part
of the frame. The power for running the fans was
generated by a 10W solar panel. A flux hose was
also used so that the inlet air would be dispersed as
far away from the outlet mouth of the frame thus
avoiding scavenging of the cool inlet air through the
outlet port. The final component used was a digital
thermometer that allowed to measure the slightest
variation in temperature accurately.

Above table, this shows the key
characteristics of these case study approaches in
their forms as well as the characteristics of mixed
research approaches. We will discuss a few of these
here.
Table 4 Case study data
In case I, when the system was not
installed, the temperature inside the car cabin
increased with a steady pace.
In case II, when the system was installed
with no coolant in it, the temperature inside the car
cabin increased with a low pace for the first 5
minutes, then increased with much higher pace to
the next 10 minutes.
In case III, when the system was installed
with acetone coolant in it, the temperature inside the
car cabin increased with a high pace for the first 5
minutes, then decreased with much lower pace to the
next 10 minutes.
In case IV, when the system was installed
with acetone coolant in it and with no flex hose, the
temperature inside the car cabin increased with a
very low pace for the first 5 minutes, then decreased
with a constant pace to the next 10 minutes and then
remained approximately constant
The solar powered heat control system was
tested taking into account different case scenarios. It
was observed that the heat control was much
observed in Case IV where the car cabin was
installed with the solar powered heat control system
containing acetone coolant and no flex hose.

VI. CONCLUSION
In this present work, Case IV when the
system was installed with acetone coolant in it and
with no flex hose, the temperature inside the car
cabin increased with a very low pace for the first 5
minutes, then decreased with a constant pace to the
next 10 minutes and then remained approximately
constant. Thus it was clear from the above case that
the temperature rise inside the car cabin was
overcome by the cooling rate offered by the system,
the device with this configuration showed very
improvement in the heat control activity. The device
works completely on green energy and showed an
average of 8.40
C reduction within a short interval
and maintained the temperature inside the car cabin
bearable for human body.
