Flowfield calculations in an MHD swirl combustor

This paper represents a computer code (SHAPE) for calculating the flow dynamics of constant density flow in the second stage trumpet shaped nozzle section of a two stage magnetohydrodynamic (MHD) swirl combustor. The code employs the stream function-vorticity approach together with the k-epsilon model of turbulence, and produces as output the flow field map of the non-dimensional stream function, axial and swirl velocity and the pressure field. Calculations are compared with the qualitative experimental results obtained from a water model. Good agreement was obtained between the experimental results and the theoretical predictions.
