| Abstract: | In the present paper the pressure splitting method is introduced into the numerical solutions for the hypersonic viscous shock layer. As a result, the marching solution difficulty of far away shock layer flow fields is overcome. An initial shock shape calculation method is presented to be used in the numerical solutions for the viscous shock layer over nonanalytical spherical cones, and it results in the simpler solution steps and higher calculation efficiency. The numerical results obtained here compare well with the experimental results of reference 20]. |
