I am trying to simulate the behavior of power cable in free ambient air. So I used two following approaches:
Approach 1: The cable has been simulated in Ansys thermal steady-state, and the convection coefficient for the outer interface of the cable has been considered.
Approach 2: The Ansys fluent has been used.
I would be grateful if you guide me on how it is possible to simulate ambient air around the cable to get the same results as the first approach to determine the cable effects on ambient air.
