[TRNSYS-users] WG: Active layer for a wall

Title: Nachricht
Dear Fuqiao,
 
The active layers are desinged to be used with water. You may change the specific heat coefficient,
but the decision of laminar/turbulent flow is based on the dynamic viscosity of water and the convective
heat transfer coeffcients from fluid to the pipe wall is based on water.
 
Thus, if you change the most important property, specific heat coefficient, and the fluid properties are
similar to water the resulting error shouldn't be too large.
 
 
Regards,
 
Marion

Betreff: [TRNSYS-users] Active layer for a wall




Dear all

Is there any way we can change the fluid properties of passing through the active layer in TYPE56? Currently default water as working fluid however you can change the specific capacity but no way to change its density, and thermal conductivity.

Any help?

Thank you in advance.
