What Is the Segregated Fluid Temperature Model?

The Segregated Fluid Temperature model solves the total energy equation with temperature as the independent variable. Enthalpy is then computed from temperature according to the equation of state.

This model is appropriate for simulations that do not involve combustion.

Properties

Convection
