The Plasma, Nonisothermal Flow () interface is used to simulate the coupling between plasma, fluid flow and heat transfer.

It combines the Plasma, Heat Transfer in Fluids, and Laminar Flow interfaces. The Nonisothermal Plasma Flow multiphysics coupling is automatically added. The flow velocity and the pressure are computed in the fluid flow interface and passed to other interfaces. The temperature is computed in the heat transfer interface and passed to other interfaces. Thermal conductivity, dynamic viscosity and other thermodynamic properties are calculated in the plasma interface and passed to other interfaces. The plasma interface calculates the enthalpy of all reactions and energy transferred to heavy species by electron impact elastic collisions and passes it to the heat transfer interface as a volume heat source.

When a Plasma, Nonisothermal Flow () interface is added from the Nonisothermal Plasma Flow branch () of the Model Wizard or Add Physics windows, Plasma, Laminar Flow, and Heat Transfer in Fluids interfaces are added to the Model Builder. In addition, the Multiphysics Couplings node is added, which automatically includes the multiphysics coupling feature Nonisothermal Plasma Flow.
