Bonjour à tous,

Étant moi-même ingénieur thermicien (dans les échangeurs de chaleur), je me demandais s’il y avait ici d’autres personnes qui travaillent dans le domaine de la thermique.

Dans quels secteurs travaillez-vous : bâtiment, industrie, automobile, aéronautique, énergie, nucléaire, électronique, chimie, procédés… ?

Je serais curieux de savoir où et comment vous appliquez thermique au quotidien.

Merci d’avance pour vos retours !

Hello everyone,

I am currently using GT-Suite for work (vapor compression cycle & heat exchangers), and I am using it on my free time as a virtual laboratory trying to simulate thermal systems.

I am currently trying to simulate a small Joule-Thomson cryocooler with nitrogen in it. I was wondering if I could have some insights (order of magnitude, equipment size, power, ...) in order to make my simulation more realistic ?

Here is the current system:

Joule-Thomson Cryocooler

Here are some results:

Evolution of the liquid volume in the accumulator

I am using now 3 stage compression with intercoolers (the compressors are running at the same speed but have different swept volume). The recuperator is very efficient (around 98%) and the expansion valve has a diameter of 0.15 mm. There is no load in that case (the final volume of liquid in the accumulator is 18%. The system is a closed loop and has about 195 g of N2 (for a total volume of 3.25 liters).

Have a good day,
