Strange results in Simulation of refrigerator condenser

[Anonymous]

Hello everyone,

the temp. distribution stopped completely at the starting of 2nd row. 

In the simulation of refrigerator condenser I have applied these conditions to the tubing:

• inlet: quality[1], temp=330K, velocity=5m/s.
• outlet: ambient pressure  (to see the pressure drop at the tube outlets).
• film coeefients on the outer surface of copper tubing= 10W/m^2/K
• heat transfer and flow is on. 

please see the results which I got and please if anyone can find the reason of this problem please help me. I have attached the screenshots of results.

I ran with a 1.5mm mesh all over (manual) and here are my temperature results.

Looks pretty OK to me. You?

CFZ attached, although this was run in 2018.

Thank you sir for your effort!   Now I will check where my setup is wrong.
