Supersonic flow around a large body in an exponential atmosphere
Tóm tắt
The problem of axisymmetric supersonic flow around a large body is solved in the case when the body is moving at constant velocity in an exponential atmosphere. The nonsteady conditions in the incoming flow are characterized by the Strouhal number. From numerical solutions for different Strouhal numbers, the deviation of the flow from quasisteady conditions is investigated.
