Defining Temperature-dependent Convection Using Ansys Mechanical

Convection is a common mode of heat transfer, which occurs in fluids. It can be simulated in two ways. One way is by using Computational Fluid Dynamics through a CFD solver, and the second way is by using a conduction-based solver. In the second approach, the convection is defined as a boundary condition driven by two parameters, film coefficient and bulk temperature. When discussing convection, the film coefficient is a very important variable. Although, the film coefficient depends on various physical attributes, a temperature-dependent film coefficient is common in thermal analyses. In this video, we will discuss about how to define temperature-dependent convection.
