Abstract : A numerical procedure developed to treat two-dimensional subsonic-transonic flow through variable area passages has been programmed for the IBM 7094 computer. This machine's computational program numerically integrates the system of equations for a thermally perfect gas providing two capabilities. The first, a design mode, will calculate the geometric configuration so that a given velocity distribution is obtained along the centerline. The second, a performance mode, will calculate the flow field associated with a given geometric configuration. This report describes the equations and numerical techniques employed, presents flow charts and specific instructions for input formats and operation of the machine program.
