Similar solutions for the hypersonic laminar boundary layer near a plane of symmetry

The laminar hypersonic boundary layer near a plane of symmetry is treated from the similarity point of view. Cases of favorable and adverse pressure gradients in the plane of symmetry and of inflow to and outflow from that plane are considered. The similarity parameters are related to physical observables so that the results may applied, at least in terms of local similarity, to determine the boundary layer characteristics in practical problems. It is found that crossflow has significant effects on the boundary layer in the plane of symmetry when the pressure gradient is adverse. (Author)
