Abstract

Abstract: Aiming at the design of the spacecraft attitude control system, a simulation software for the rigid-liquid coupling calculation of the liquid-filled spacecraft is built on the basis of the open source CFD software OpenFOAM. In the moving boundary problem, the N-S equation in the non-inertial frame is derived to improve the calculation efficiency, which avoids a large number of grid conversion calculations of the moving grid method in the traditional CFD software. PIMPLE algorithm is used to build the sloshing dynamics solution module, and the variable step length Runge-Kutta method is used to build the attitude movement module, and the rigid-liquid coupling simulation of the spacecraft based on the CFD method is realized. Numerical simulations on related examples are carried out, which are coincident with the calculation results of the rigid-liquid coupling program based on the equivalent mechanical model and commercial software.
