This paper discusses the CFD optimization of a special purpose carburetor design for use with low energy density gases like producer gas at low operating pressures. The carburetor aims to generate an optimal air-fuel mixture under varying engine load conditions and fuel supply pressures. A CFD simulation model of the carburetor mixing chamber is analyzed to optimize the geometry for efficient mixing and minimal pressure drop. The optimized design aims to standardize carburetors that can address the technology gap in using low energy density fuels in engines.

2. About the Department
The Department of Mechanical Engineering started in the year 1979, has now
grown into a full-fledged Department offering undergraduate and Post
Graduate courses in Mechanical Engineering with the present intake of 120
students. The Department also offers two Post Graduate courses, M.Tech. in
Design Engineering and M.Tech. in Computer Integrated Manufacturing. There
has been a significant improvement in quality, stature, infrastructure and other
facilities.
The department is a recognized Research Centre under VTU and 8 research
scholars are working for their Doctoral research. The department has to its
credit many funded projects from leading organisation like AICTE, Naval
Research Board, Institution of Engineers, etc.
The department has so far graduated more than 4200 Mechanical Engineers
who are contributing significantly to the development and running of various
public and private organizations in India and abroad in the fields of Academics,
Research, Industrial and Social sector.
The Department of Mechanical Engineering is Accredited for 5 years by

Industrial uses of these equipments may be
divided into two categories:
 Basic material research
 Final product or component testing.
Material research is mainly concerned with
developing and testing a material for certain
physical properties, such as high strength
characteristics at elevated temperatures. It is
responsibility of those involved in the product
testing to subject a product or a component in its
final geometric form to the conditions that closely
simulate the end use.
The two areas, material testing and product
testing have different requirements and yet the
tests can be completed with the same type of
equipments. In many cases the test arrangement
and performance requirement are difficult but the
equipment is basically the same.
Electro Hydraulic closed- loop systems are
dedicated to producing realistic tests so materials

service use. This requires equipment capable of
reproducing a program to a high degree of
accuracy as-well-as being adaptable to perform
many different types of tests. These systems have
been developed and proven for many types of
applications. The basic principle of closed loop

Entry requirements for higher education
in Germany:
Applying for any course in a German
University is very straight forward and hassle free.
All international students applying for English
taught Master’s course in German universities is
required to prove their English language capability,
with a good TOEFL or IELTS score. Although, the
courses are offered completely in English, its
highly advised for students to learn German up to
intermediate proficiency in both speaking and
writing, which will help students socialize and
more importantly increase their prospects in
search of Projects and Jobs. GRE is not mandatory
for most of the universities, but considering the
increase in competition it could well decide your
fate. Any paper presentations or involvement in
some research activities could boost your profile.
So, all my fellow juniors at DSCE, I would like to
wish you all a great fun and success during your
bachelors and also for your future prospects. With
my above article I have tried to share some
information about higher education in Germany,
which I hope would be useful for all those who
wish to study further in Germany. If any of you
want to get more information on the same you
could contact me any time and I would be more
than pleased to help you out.
I would like to thank Prof. Dr.C.P.S Prakash for
providing me an opportunity to share my thoughts
about higher education in Germany.
Wish you all success.

Acceleration
The 2006 F1 cars have a power-to-weight ratio of
1,250 hp/t Theoretically this would allow the car
to reach 100 km/h (60 mph) in less than 1 second.
However the massive power cannot be converted
to motion at low speeds due to traction loss and
the usual figure is 2 seconds to reach 100 km/h
(60 mph). After about 130 km/h (80 mph) traction
loss is minimal due to the combined effect of the
car moving faster and the down force, hence the
car continues accelerating at a very high rate. The
figures are
0 to 100 km/h: 1.7 seconds
0 to 200 km/h: 3.8 seconds
0 to 300 km/h: 8.6 seconds*

How is the stored energy released by the driver?
The regulations stipulate that the release must be
completely under the driver’s control. There is a
boost button on the steering wheel which can be
pressed by the driver.
.
What is KERS?
The acronym KERS stands for Kinetic
Energy Recovery System. The device recovers the
kinetic energy that is present in the waste heat
created by the car’s braking process. It stores that
energy and converts itinto power that can be
called upon to boost acceleration.
How does it work?
There are principally two types of system - battery Why was KERS introduced?
