“…In a gap, there are complicated vortex motions caused by the boundary-layer flow, so the gap flow is difficult to be studied by theory analyses. Up to now, the majority of researches about the gap flow have been done by NASA [8][9][10][11][12][13][14]. The NASA studied some influences on heat flux in a gap in experiments which were based on hypersonic wind tunnel tests and arc jet tests.…”

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.
