Godunov method and computer program to determine the pressure and flow field associated with a sonic boom focusA computer method has been developed to calculate the flow field associated with sonic boom focusing. Solutions are obtained for focussing caused by localized cold spots in the atmosphere, as well as for N-waves with concave fronts. Results include focus factors and the length scales of the focal region. Both strong and weak shock waves are studied.
