In this paper, a scheme based on Essentially Nonoscillating (ENO) has been developed into an implicit finite volume procedure, which uses pressure as a working variable. The boundedness criteria determined from ENO schemes. This numerical process is used for solution of Euler equations on a nonorthogonal mesh with collocated finite volume formulation. The developed scheme is applied to the computation of steady subsonic and transonic flows over a bump-in-channel geometry as well as to the transient shock-tube problem. The results of the ENO scheme are compared with analytical and other computations published in literature.
