摘要

A numerical investigation is carried out using an Open source solver for a hypersonic flow around a space capsule. Calculations are performed to test the reliability of the solver to simulate Martian reentry flows. The kinetic model and viscosity coefficients have been added to the solver library. A mesh study for the fore-body concluded that a medium mesh was sufficient to capture the shock standoff distance with remarkable accuracy, which leads us to believe that the numerical scheme used is quite robust. The study then focused on the effect of wall condition on the flow topology and proved once again that the solver could accurately take the influence of boundary conditions on flow parameters. Following the obtained results, hy2Foam can be considered as a reliable tool for numerical simulations of space capsules reentry.
