Transparent conditions on front and back crossections of windtunnel for time-dependent subsonic induscid flow problem
Abstract:
Euler equations system in infinitely long windtunnel is considered. The flow domain is bounded by front and back boundaries. The non-local conditions on the boundaries, which are transparent for penetration of disturbances described by Euler equations linearised with respect to uniform flow are suggested. The conditions permit to pass from an input problem in infinitely long windtunnel to a problem in a finite domain. The equivalence of these problems for linearised equations is proved.
