Hi Ansys Team, I hope this message finds you well.<\/p>\n

I need to simulate the heating process of an air stream flowing inside a metallic pipe. The pipe is subject to a voltage potential, making electricity flow across the metal, releasing heat by the joule effect. The heat released is absorbed by the air stream, increasing its temperature. The outlet temperature of the air stream is in the range 800C – 1000C, while the pipe can reach 1100C – 1200C at its hottest point. The diameter of the pipe is in the range of 0.5in – 5in. Please find attached a representation of the process<\/p>\n

Given the high temperature of the process and the small diameter of the pipe, gas might enter the turbulent regime. However, I am not sure what turbulence model would be the most appropriate to use for the simulation. Maybe K-epsilon, or maybe K-omega SST?<\/p>\n

Could you please help me with this? \ud83d\ude42<\/p>\n

Thank you<\/p>\n
