Stirling Forum Home Page

Dear,



My name is Turan. I’m a mechanical engineering student at Middle East
Technical
University in Turkey. For our senior design project we are going to
design and
manufacture a Stirling engine. We have been searching the web
database and some
books for about 2 weeks and the literature survey is almost OK. The
most
important stage is to decide on the engine we are going to design and
make the
corresponding analysis. Unfortunately Stirling engines are not
widespread and it
is difficult to choose the one that fits well to the specifications
of our
department. As an idea I want to ask for your opinion. General
specifications
and criteria is written below:



The designed Stirling Engine System must be able to generate a
constant DC
voltage for a given input power of 50 watts generated by an
electrical heater
for 220 V. Also an additional control system will control the output
of the DC
generator and provide constant voltage speed and minimum fluctuation
of the
voltage which is the further stage of the design. A flywheel is
required to
provide momentum to bring the engine through a full cycle. The model
scale is
going to be manufactured in 1:1 scale.

Design Criteria

Minimum speed fluctuation (%25),

Minimum time to bring the output speed to steady-state (%25),

Maximum efficiency (%30),

Minimum weight (%10),

Minimum size of the engine (%10).



What are your suggestions? Thanks for your interest...

Your project appears to have been selected to allow for a sucessful completion.

Stirling engine speed can not, generally, be regulated like other engines. It is interdependent on the hot and cold end temperatures as well as the specific design details and materials of construction.

Stirling engines fall into two classes. Commercial units made for specific applications are made for a specific market and are usually quite expensive. The others are units made by hobbyists or commercially manufactured as expensive 'toys.'

It may be necessary to design and build two or three engines to confirm your design details prior to the final product.

Best wishes for a sucessful conclusion to your project.

hi thanks for your answer
I DONT HOVE MANY DATA ABOUT Stirling ENGINE. I READ ABOUT IN A BOOK
IWANT OF YOU EXPLINE ABOUT IT THANK
