Hello Everyone,
I am try to find heat absorbed by the tube as shown in the photo below. liquid at room temperature is flowing through the pipe and hot flue gases are passing around the tube. I am using conjugate heat flow as there are to fluids involved. But not getting enough heat flow to the tube.
Can any one please help me and tell me what am I doing wrong?
Please do inform me if this is the right way of doing heat flow study in this case.
If you have want to go through the study, Please let me know I can send you the model; not attaching the file as the zipped file exceeds the limit.
Hi Samarth,
According to the boundaries defined in your Flow Project tree you only have fluid movement defined in the chamber outside the tube. The inner fluid subdomain does not appear to have any boundaries for a fluid inside the tube itself that would approximate your description of "liquid at room temperature is flowing through the pipe". You probably want to start by adding additional boundary conditions to the fluid subdomain so fluid is moving through your tubes.
Once you have fluid moving through your tubes you would just be measuring the outlet temperature vs the inlet temperature of the fluid subdomain to find the heat power being removed from the system.
