Research on Flow Field and Temperature Field Characteristics of One Rocket Charge with Complicated Structure by Numerical Method
The paper researches flow field and temperature field characteristics of one rocket charge with complicated structure by numerical method.The charge, in which there exist the conduction, convection and radiation, consists of the metal shell, seven propellant columns and air gaps.For the reasons, to solve temperature field of the charge is to solve a complex heat transfer problem in a complicated calculation region.A mathematical and physical model for the flow and heat transfer process in the charge is established and unstructured meshes are applied to disperse the complicated calculation region.The SIMPLE algorithm is used to solve the partial differential equations, and the calculation results are in good agreement with the experimental data.On basis of the numerical simulation, the flow field and temperature field characteristics of the charge are researched and subsequently some valuable conclusions are gotten.
