Compressible
Flow Analysis
Compressible flow occurs in many applications such as
flow in turbine engines, flow over supersonic aircrafts and rockets.
The flow behaviors consist of shock wave, expansion wave and
shock-shock interaction phenomena. These phenomena are com-
plicated and difficult to predict by numerical methods in the past.
Fluent in ANSYS contains analysis capability that can provide
solutions representing such complicated phenomena effectively.
In this chapter, we begin with the conservative equa-
tions of the compressible flow. Theoretical background of the cell-
centered method for compressible flow analysis is presented.
Capability of Fluent is demonstrated by analyzing academic pro-
blems that have analytical solutions. Application example is also
presented to highlight complicated compressible flow behaviors.
