Numerical study on aerodynamic heat of hypersonic flight
Accurate prediction of the shock wave has a significant effect on the development of space transportation vehicle or exploration missions. Taking Lobb sphere as the example, the aerodynamic heat of hypersonic flight in different Mach numbers is simulated by the finite volume method. Chemica...

description |
Accurate prediction of the shock wave has a significant effect on the
development of space transportation vehicle or exploration missions. Taking
Lobb sphere as the example, the aerodynamic heat of hypersonic flight in
different Mach numbers is simulated by the finite volume method. Chemical
reactions and non-equilibrium heat are taken into account in this paper,
where convective flux of the space term adopts the Roe format, and
discretization of the time term is achieved by backward Euler algorithm. The
numerical results reveal that thick mesh can lead to accurate prediction, and
the thickness of the shock wave decreases as grid number increases.
Furthermore, most of kinetic energy converts into internal energy crossing
the shock wave. |
