Abstract

The influence of the coefficient of bulk viscosity on the distribution of normal stress on a sharp edge was analyzed. The problem is solved of air flow over a thin plate ( , , ). It is shown that at Mach and at the value of the coefficient of bulk viscosity , the distribution of normal stress is described by smooth curves. At high Mach numbers, the results are physically inadequate for any value of .
