•Energy transport equation:

–Energy E per unit mass is defined as:

–

–

–

–Pressure work and kinetic energy are always accounted for with compressible flows or when using the density-based solvers. For the pressure-based solver, they are omitted and can be added through the text command:

–

–The TUI command define/models/energy? Will give more options when enabling the energy equation.

•Five thermal conditions

–Heat Flux

–Temperature

–Convection – simulates an external convection environment which is not modeled (user-prescribed heat transfer coefficient).

–Radiation – simulates an external radiation environment which is not modeled (user-prescribed
external emissivity and
radiation temperature).

–Mixed – Combination of
Convection and Radiation
boundary conditions.

can  be defined for 1D or
