UNO SCHEME FOR STEDY AND TRANSIENT COMPRESSIBLE FLOW IN PRESSURE-BASED METHOD

In this paper, a scheme based on Uniformally Nonoscillating (UNO) has been developed into an implicit finite volume procedure, which uses pressure as a working variable. The boundedness criterion is determined from UNO scheme. The numerical process is used for slution of Euler eauations on a nonorthogonal mesh with collocated finite colume formulation. The developed scheme is applied to the computations pf steady supersonic flow over a bump-in-channel geometry as well as to the transient shock-tube problem. The resulte of the UNO scheme compared with analytical and other computations published in literature.
