Convection

The Convection condition causes convective heat transfer to occur through one or more flat or curved faces (in contact with a fluid).

To define a convection load, specify a constant value for the heat transfer coefficient (also called the film coefficient). This value is based on the composition of the fluid in contact with the face, the geometry of the face, and the hydrodynamics of the fluid flow past the face. Then enter the external temperature, which is the temperature of the surrounding fluid.
