Abstract
A 3D (three dimension) flow and heat transfer in a nozzle cavity mathematical model has been developed with a low Reynolds k - e turbulent model in this paper. The established mathematical model are simulated by computer,and the laws of velocity and temperature distribution in the nozzle cavity has been achieved. The simulation results are in agreement very well with the results of the measurement. According to the simulation result,the size of the nozzle cavity edge are changed. Then the improved nozzle cavity was simulated,and the results showed the velocity distribution more reasonable and the temperature difference between the edge and the middle of the nozzle export has been reduced,and it is proved in the actual industrial production.
