In calculations of transonic flows it is necessary to limit the domain of computation to a size that is manageable by computers. At the boundary of the computational domain, boundary conditions are required to ensure a unique solution. Since wave solutions exist in the unsteady transonic flow field,

A hybrid boundary element -finite volume method for unsteady transonic flow computation has been developed. In this method, the unsteady Euler equations in a moving frame of reference are solved in a small embedded domain (inner domain) around the airfoil using an implicit finite volume scheme. The
A modified "triple-deck" model is proposed to investigate free unsteady viscid-inviscid interaction at transonic velocities. The modification of the model is the inclusion of the singular term of the transonic expansion, thanks to which the Lin-Reissner-Tsien equation can be refined and a more accur
