Turbulent flow calculation for a tail-pipe nozzle using multiblock algorithm and finite volume method

Based on axisymmetric two dimensional N S equation, finite volume method and multiblock algorithm were used to study turbulent flow for a tail pipe nozzle,providing thermal environment for the design of anti thermal construct. The flow field was investigated and some properties of the distribution of temperature, pressure and Mach number of gas in nozzle and temperature of gas along the wall were obtained. From the calculation and analysis,some suggestions were put forward for the design of anti thermal construct.
