Design of PVC Bladed Horizontal Axis Wind Turbine for Low Wind Speed RegionIJERA Editor
The Project is aimed at designing a wind turbine that can be able to build by Laypersons, using readily available material which is feasible & affordable to provide much needed electricity. Since most of the high wind power density regions in the zone of high wind speed are already being tapped by large scale wind turbine and so it required creating a large scope for the development of low wind speed turbines. Our study focuses primarily on designing the blade for tapping power in the regions of low wind power density. The aerodynamic profiles of wind turbine blades have major influence on aerodynamic efficiency of wind turbine. This can be achieved by comparing the effectiveness of a crude blade fashioned from a different Size, Material & standard of PVC drainage pipe which are easily available in market. It can be evaluated by performing experimental analysis, data collection & its evaluation on different type & size of PVC Pipe & preparing an analytical tool for best Design.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

2. 4.0 Literature Review :
1. D.A. Nikam et al. analyzed the literature review on design and development of vertical
axis wind turbine blade. This paper explains that the wind mill such as vertical and
horizontal wind mill is widely used for energy production. The horizontal wind mill is
highly used for large scale applications which require more space and huge
investment. Whereas the vertical wind mill is suitable for domestic application at low
cost. The generation of electricity is affected by the geometry and orientation of the
blade in the wind turbine. To optimize this by setting the proper parameter for the
blade design. The experimental result indicates that the blade plays critical role in the
performance and energy production of the turbine. The optimized blade parameter and
its specification can improve the generation of electricity.
2. Vivek Cm analyzed the literature review Wind energy is one of the major forms of
renewable energy resources found abundantly which is widely used as an alternative
energy. Wind power is sustainable and the production of electricity using wind energy
is increasing day by day due to lack of availability of fossil fuels. The energy can be
converted into electricity by using vertical axis wind turbine (VAWT) and Horizontal
axis wind turbine (HAWT). The vertical axis wind turbine is highly used for domestic
applications where the volume of production is low and efficiency is optimal while the
horizontal axis wind turbine is widely for larger volume of production requires huge
investment and the efficiency is high. This paper focused on increasing the efficiency
of using wind energy by producing large amount of electricity and reduces the space
for installation. This can be done by combining the vertical axis wind turbine (VAWT)
and horizontal axis wind turbine (HAWT) in a same tower. The combined vertical and
horizontal axis wind turbine reduces the cost for larger volume of electricity
generation

3. ➢ Project Details
Define Wind Energy :
Wind energy is a form of solar energy. Wind energy (or wind power) describes the
process by which wind is used to generate electricity. Wind turbines convert the
kinetic energy in the wind into mechanical power. A generator can convert mechanical power
into electricity.
Type of wind turbine :
i. Horizontal Axis Wind Mill
ii. Vertical Axis Wind Mill
Horizontal Axis Wind Turbine
The horizontal axis wind turbine
(HAWT) is widely used for higher volume
of production which requires huge
investment and occupies more space for the
installation compared with vertical axis
wind turbine (VAWT). The rotational axis
of horizontal axis wind turbine is parallel
towards the direction of wind in order to
generate electricity . It requires large tower
and blade to install and the transportation
cost is nearly 20% of the equipment of the
cost. Highly skilled labours are required to
install the horizontal axis wind turbine. The
production cost is low when generating
higher volume of electricity. The efficiency
of horizontal axis wind turbine is high than
the vertical axis wind turbine. The
horizontal axis wind turbines are most
suitable for sea shores, hill tops etc.,
➢Construction and Working of Components
Tower:
A tower that supports the nacelle and rotor hub at its top. These are made from tubular
steel, concrete, or steel lattice. Height of the tower is an important in design of HWAT.
Because wind speed increases with height, taller towers enable turbines to capture more
energy and generate more electricity. Generally output power of the wind system increases
with increase in height and also reduces the turbulence in wind. The theoretical view of tower
height versus power out is shown in figure 7 . click on the link to get more about size of the
towers
4. Blades:
Wind turbine blades are used to extract the kinetic energy of wind and convert to
mechanical energy. These blades are made up of fiber glass-reinforced polyester or wood-
epoxy. Wind turbines have one or two or three or multiple blades based up on the
construction. Most of the HAWT have three blades. These are connected to rotor hub.
Multiple blade concept is used in earlier days for pumping water and grinding etc.
Nacelle:
A housing which contains all the
components which is essential to operate
the turbine efficiently is called a nacelle.
It is fitted at the top of a tower and
includes the gear box, low- and high-
speed shafts, generator, controller, and
brakes. A wind speed anemometer and a
wind vane are mounted on the nacelle.
Hub :
A rotor hub is provided for
coupling a wind turbine rotor blade and a
shaft. The hub assembly consists of hub,
bolts, blade bearings, pitch system and
internals . Rotor hubs are made with
welded sheet steel, cast iron, forged steel.
The types of rotor hubs are
• Hinge-less hub
• Teetering hub
5. Drive shaft :
Drive shafts are a hollow or solid steel
hardened shaft under very high stresses and
considerable torque. Drive shafts are used to
transfer rotational mechanical energy from
blade hub to the generator to produce
electricity. A wind turbine normally consists
two shafts .
Main shaft:
It is connected between blade hub and input to the gear box. It rotates at low speeds.
So, it is also called as 'low speed shaft'.
Generator shaft:
`It connects the gear box output to the generator input. It rotates at very high-speed
equals to the rating of the generator. It is also called 'high speed shaft'.
Generator:
The output rotational mechanical energy of the gear box is connected to the generator
through generator shaft. It works on the principle of 'Faraday's law of electromagnetic
induction". It converts mechanical energy into electrical energy.
Gear box :
Gear box used in wind
energy systems to change low
speed high toque power
coming from a rotor blade to
high speed low torque power
which is used for generator. It
is connected in between main
shaft and generator shaft to
increase rotational speeds
from about 30 to 60 rotations
per minute (rpm) to about
1000 to 1800 rpm. Gearboxes
used for wind turbine are
made from superior quality
aluminum alloys, stainless
steel, cast iron etc.
The various gear boxes used in wind turbines are
1. Planetary Gearbox
2. Helical Gearbox
3. Worm Gearbox
6. Advantages
1. The tall tower base allows access to stronger wind in sites with wind shear. In some wind
shear sites, every ten meters up the wind speed can increase by 20% and the power output
by 34%.
2. High efficiency, since the blades always move perpendicularly to the wind,
receiving power through the whole rotation.
Disadvantages
1. The tall towers and blades up to 90 meters long are difficult to transport. Transportation
can be 20% of equipment costs.
2. Tall HAWTs are difficult to install, needing very tall and expensive cranes and skilled
operators.
3. Massive tower construction is required to support the heavy blades, gearbox, and
generator.
Applications
It is used generate electric energy from wind energy. Allowing the angle of attack to be
remotely adjusted gives greater control, so
the turbine collects the maximum amount of wind energy for the time of day and season.
