Supersonic Inlet

Use the Supersonic Inlet simulation object to model fluid entering the domain at supersonic velocity.

As with creating an Inlet Flow type of Flow Boundary Condition simulation object, you define a Supersonic Inlet on a bounding surface of the fluid domain, adjacent to the fluid elements. You can define flow only in terms of Mach number (velocity / speed of sound).

• You can define Temperature and Pressure Inlet Conditions as equal to those defined on the Ambient Conditions page in the Solution dialog box, or you can specify values for these conditions.

• The flow direction is normal to the Supersonic Inlet surface by default. You can specify a different flow direction by defining a vector at any angle. The fluid moves at the specified Mach number along the vector.

• You can specify the turbulence properties at the inlet or they can be calculated automatically using the specified turbulence model. For more information, see Understanding the turbulence models.

• The energy equations account for the viscous heating effects and transient pressure terms.

• Thermal wall functions account for viscous heating.
