Axi-Symmetric Thermal Analysis of Regenerative Cooled Cryogenic Engine Nozzle Using Fem

Abstract

An axi-symmetric thermal analysis on the cooling channels of a regenerative cooled cryogenic engine nozzle is carried out.Taylor Galerkin Finite Element Method is used as a means for spatial & time discretization of the energy equation in cylindrical coordinate system. Numerically simulated results for temperature distribution in the nozzle wall is obtained for a given set of mass flow rate of coolant and hot gas side heat transfer coefficients, set as boundary conditions . The results obtained are used to determine the optimum mass flow rate of coolant required for the proper functioning of the engine.
