Abstract
This paper presents a study of typical cooling jacket for liquid propellant rocket engine (LPRE). Initially semi-empirical calculation was performed, to specify the boundary conditions of heat flux provide by combustion. Posteriorly the temperatures of walls and pressure drop on the cooling jacket were calculated. The geometry and mesh of the cooling jacket were design on parametric software and then analyzed the conjugate heat transfer in OpenFOAM CFD software, with the same boundary conditions considered on semi-empirical calculation. The results of numerical and semi-empirical calculation achieved were confronted. Finally it were possible to correct the semi-empirical calculation, according to proposed literature, considering that numerical calculation returned the reliable result and next of experimental analysis. This study is the first step to align the semi-empirical calculation with CFD modeling. The next step will be align both with experimental study. The confront this results possible close the cycle of the modern engineering approach, creating a strength tool of thermal analysis applied on liquid propellant rocket engine.
