Convective Heat Losses
The Convective Heat Losses node is available when the Compute particle temperature check box is selected in the physics interface Additional Variables section. Use the Convective Heat Losses node to model the heating or cooling of a particle due to convective heat exchange with the surrounding fluid.
The temperature within the particle is assumed to be uniform; that is, heat transfer by conduction within the particle takes place on a much shorter time scale than heat transfer by convection at the surface. This is equivalent to the assumption that the particle Biot number is much smaller than unity, and allows each particle’s temperature to be stored as a single number instead of a temperature distribution.
Convective Heat Losses
Enter a Heat transfer coefficient h (SI unit: W/(m2 K)). The default is 0. Enter a value or expression for the Temperature, T (SI unit: K), or if the temperature is computed by another physics it can be selected from the list. The default is 293.15 K.
