Transmission is a part of the car which connects the engine to the wheels. When car speeds up, the engine can not speed up in the same proportion, so there are gears involved which match the engine speed to the wheel speed so that we can drive faster or slower than the engine speed.
CVT transmission can change seamlessly through an infinite number of effective gear ratios between maximum and minimum values giving jerk free driving experience.
In this presentation we mainly discuss about Variable-diameter pulley (VDP) and how basically it functions.

WASTEWATER TREATMENT METHODS- EFFECTS OF WW ON SOILpgayatrinaidu
Domestic or sanitary wastewater. This comes from residential sources including toilets, sinks, bathing, and laundry. It can contain body wastes containing intestinal disease organisms.
Industrial wastewater. This is discharged by manufacturing processes and commercial enterprises. Process wastewater can contain rinse waters including such things as residual acids, plating metals, and toxic chemicals.
Wastewater is treated to remove pollutants (contaminants). Wastewater treatment is a process to improve and purify the water, removing some or all of the contaminants, making it fit for reuse or discharge back to the environment. Discharge may be to surface water, such as rivers or the ocean, or to groundwater that lies beneath the land surface of the earth. Properly treating wastewater assures that acceptable overall water quality is maintained.
In many parts of the world, including in the United States, health problems and diseases have often been caused by discharging untreated or inadequately treated wastewater. Such discharges are called water pollution, and result in the spreading of disease, fish kills, and destruction of other forms of aquatic life. The pollution of water has a serious impact on all living creatures, and can negatively affect the use of water for drinking, household needs, recreation, fishing, transportation, and commerce.

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.

3. WHAT IS TRANSMISSION ?
Transmission is a part of the car which connects the engine to the
wheels. When car speeds up, the engine can not speed up in the same
proportion, so there are gears involved which match the engine speed
to the wheel speed so that we can drive faster or slower than the
engine speed.
4. TYPES OF TRANSMISSION
1. MANUAL TRANMISSION
• The selection of gear ratios on manual transmissions is accomplished by manually
shifting a gear selector mechanism that disengages one gear and selects another.
Most modern types of this transmissions have five or six forward (and one
reverse) gears.
• This type of transmission is connected to the engine via a clutch, which if
disengaged (by pressing the foot pedal or hand lever), removes torque from the
system.
2. FULLY AUTOMATIC TRANSMISSION
• In an automatic transmission, the
hydraulically operated control systems are
managed electronically by the vehicle’s
computer instead of the clutch and gear stick.
• All the driver has to do is shift the selector
from Park (P) or Neutral (N), into Drive (D),
and the gear shifting will take place
automatically and smoothly, without any
additional input from the driver under
normal driving conditions.
5. 3. SEMI-AUTOMATIC TRANSMISSION
• Also known as an “automatic manual” or
“clutch less manual” transmission, the simplest
way to describe this type is to call it a hybrid
between a fully automatic and manual
transmission.
• However, there is no need to operate a clutch
pedal. Processors, sensors, pneumatics and
actuators are all used to “automatically” shift
the gears once the drive has signaled the
change.
4. CONTINOUSLY VARIALBLE TRANSMISSION
(CVT)
• Instead of gears, the system relies on a
rubber or metal belt running over pulleys
that can vary their effective diameters.
• To keep the belt at its optimum tension, one
pulley will increase its effective diameter,
while the other decreases its effective
diameter by exactly the same amount.
6. WORKING OF AUTOMATED TRANSMISSION
• Gear selection in automatic transmissions depends on many operational
conditions, such as vehicle speed, engine speed, performance mode (where
fitted) selected as well as driver assist systems such as traction control,
stability control, automatic/autonomous braking and cruise control.
7. • Fluid is automatically channeled to mechanisms that drive sets of
planetary gears and clutches, which are roughly analogous to the gear
ratios found in in this type of transmission.
• Rotational energy is provided by a torque converter, a mechanism
consisting of two freely rotating parts.
• One half is attached to the engine and the other to the transmission
input shaft. The two halves of the converter are positioned very
closely together.
• The fluid that circulates between them is influenced by the rotational
energy of the engine which in turn impacts the transmission side of
the converter.
• Torque is transferred from the engine to the transmission thanks to
the shearing strength of fluid.

10. PROS AND CONS OF AMT
ADVANTAGES-
• Very easy to use.
• Provides a comfortable driving experience.
• Modern automatic transmissions match manual transmissions in terms of
performance and fuel economy.
DISADVANTAGES
• Complex and prone to failures, malfunctions, and unsatisfactory performance
due to a variety of possible issues, some of which are unrelated to it itself.
• More expensive than a manual transmission to maintain over a vehicle’s
lifetime.
• Expensive to repair. Replacement is often the more cost effective option.
• Unsuitable for use in off-road environments because it cannot provide engine
braking.
11. ALTERNATIVE TRANSMISSION SYSTEMS
• If cost of the transmission can be overlooked (such as in
performance or luxury cars), there are even better systems
which are available. These systems cars called Dual-Clutch
Automatic transmission systems.
• The way they operate is that instead of one, they use two-
clutches which connect with even and odd number of gears.
• When the car speed changes, the transmission system
(controlled by a microprocessor unit), selects a
gear (depending on load, speed, driver’s throttle input and
many other factors). This process is very fast & efficient.
12.
13. CONCLUSION
• The latest generation of AMT is known as “mechatronic”, as for
the first time, it combines the electronic control part and the
hydraulic actuation part of the transmission in a single kit.
• This allows considerable improvements to performance, both in
terms of speed and comfort when changing gear.
• This is the latest step in the evolution of a product which was
first introduced to the car market with the Ferrari 355 F1 in July
1997. The product is still undergoing “sharp” growth in
performance.
