my science Fair with ISEF is coming up is there any experiments that could bepossibly used with a heat engine if you have an idea can you post hear please thanks

I’ll cover the temperature ratio vs pressure ratio question in a post soon. If the pressure ratio gets too high for the temperature ratio, you end up doing a lot of adiabatic heating and cooling during the compression and expansion cycles and get less power out of the engine. You can use Stirling engines as a heat pump by putting power into the crankshaft.

you say that keep the pressure ratio less than or equal to the temperature ratio for successful stirling engine. What do you know that? and Can you tell me about theory or all of equation or something else that you use to make stirling engine simulator? The thing is,I want to design beta type stirling engine but I’m not assured of my desing that it can be success. I’m waiting for your reply.Thank you very much. You can send file to my e-mail.

The temperature ratio is the ratio of two temperatures measured on an absolute temperature scale (either degrees Kelvin or degrees Rankine). When I compute the temperature ratio in the simulator it will be T(hot)/T(cold).

Dead volumes are those volumes that are not swept by either the displacer or the power piston. The hot dead volume normally only occurs at the hot end of the displacer cylinder where there is some clearance to keep the displacer from striking the end of the cylinder. The cold dead volume is the same at the cold end plus any dead volume connecting the cold end of the displacer to the power cylinder. The cold dead volume would also include any clearance between the top of the power piston and the end of the power cylinder when the piston is at its extreme compression position.

I would like to ask you questions as follows;
- what is equation to be found the temperature ratio?
- what is the position of dead volume(hot and cold)?(Could you please present by picture?)

It is really important for my education. I would appreciate your urgent response.Thank you very much.

[...] Tc. Using these values yields the first computed row in the table below. This simulator makes some idealized assumptions that make it virtually impossible for the real engine to output more power than the simulator. I [...]

I got hooked on the idea of giant pistons after looking at LNG and water tanks. Investigated some low friction liner materials for while. Maybe to capture direct solar or energy displaced by standing buildings. Very interesting website.
