Temperature profile stimulation
Temperature profile stimulation
(OP)
Hi all,
I wonder if it is possible to stimulate a temperature profile of a heat exchanger by only using common software such as matlab, polymath etc. I been looking back in my books but I failed to find a way to do so. If anyone knows, please help me out!
Thank you

I hope I make it better to understand this time, thank you very much for your help.

Why not correlate time in the coil to a variable area that the fluid has seen and then calculate the T using the usual heat transfer equations with the known variable amount of heat transfer area.
Good luck,

RE: Temperature profile stimulation
As Latexman mentioned, I am able to calculate the outlet T using heat transfer equation but I also want to find out the whole process. What I don't understand is how to the correlate the temperature with time during the whole process in my case.

Assume it is a stainless steel 316, ID 10mm OD 12mm, with the water flow rate of 250ml/min. The inital product temperature is about 35C, and the hot water bath is 85C. Coil length is about 2m long. I think that's what I used to calculate the water outlet temperature, but I also want to know how long, and how does the temperature changed with the coil from beginning til end.

I actually have tried this method before as well, but I ended up getting the product instantly shoot to 80ish already in the first few chunk (0.1m or similar distance). I am not sure if I am doing something wrong in my calculation or the coil just allow such quick heat transfer.
