Modelling combustor turbine interaction is to be performed in an integrated simulation of a combustion chamber and the nozzle guide vane of a jet engine. Starting with an incompressible pressure based combustion CFD code, two steps are required to obtain a code that is suitable for performing such calculations. Firstly, the SIMPLE algorithm needs to be extended to all-Mach-number flows. Secondly the solution algorithm needs to be modified to deal with combustion. This paper presents the first of these steps. A solver has been developed which is capable of computing both incompressible and transonic flows. Validation of modelling compressible viscous flow is performed using experimental data. The suitability of the algorithm to highly complex geometry is demonstrated on real engine nozzle guide vane geometry and results are compared to the results of other solvers.
