The geometry is sketched out in the following diagram. /////// ////// *******/// ///// ** * // wall ////// * ---> zero ---> * //////// * pressure * * ---> ---------> ---> ************************************************ //////////////////////////////////////////////// The inlet conditions are prescribed total pressure and total temperature at a Mach Number of 0.5. The design outlet Mach number is 2.0 for which Pex/Po,in = .1278. The exit boundary condition corresponds to a fixed pressure at the expected nodal Mach number. A system of units is chosen whereby the flow variables can be interpreted as: P/Po,in ; RHO/RHOo,in ; T/To,in ; and U*SQRT(GAMMA)/Ao. Here, Ao is the acoustic velocity at the stagnation temperature. enddis ************************************************************ Group 1.
