Re: [TRNSYS-users] Piston modelling on Trnsys

Grégoire,

 I am not aware of any existing models. If the equations that govern the piston are simple enough then you can enter them as equations in the Simulation Studio project. If they are more complex then you would need to write a new TRNSYS Type. If you are using Trnsys18 there is a dedicated Fortran compiler (called TypeStudio) built in to TRNSYS. If you are using an earlier version of TRNSYS then you will need to obtain an external Fortran compiler in order to write the component. A third alternative would be to develop the piston model in EES, Excel, or Matlab and then use the appropriate TRNSYS Type to communicated between Trnsys and the external model.

kind regards,

 David

Dear all,


I'm trying to modelise a Stirling engine on Trnsys. I chose to break it down into its constituent parts, because there is not a complete Stirling Engine Component available on this software.


However, I don't know how to modelise the piston part of Stirling cycle. I would like to modelise this part with a tank and a piston inside it. Regarding the inflow temperature, air will expend and push the piston.


Yours faithfully,


Grégoire CHAIX
