AB - Accurate prediction of aerodynamic and thermal environment around a gap has a  significant effect on the development of spacecraft. The implicit finite  volume schemes are derived and programmed from Navier-Stokes equations.  Taking the gap between thermal insulation tiles as an example, a numerical  simulation is performed by the finite volume method to obtain the flow  characteristic in a gap and then to analyze the heat transfer mechanism. The  numerical results are consistent with the experimental ones, which prove the  precision of the method used in this paper. Furthermore, the numerical  results reveal that the heat convection plays a leading role in heat  transfer around a gap.
