APPLICATION OF UNO SCHEME FOR STEADY AND TRANSIENT COMPRESSIBLE FLOW IN PRESSURE-BASED METHOD
Year
: 2008
Abstract: A pressure_based implicit procedure to solve the Euler equations on a nonorthogonal mesh with
collocated finite volume formulations is described which uses pressure as a working variable. The
boundedness criteria for this procedure are determined from Uniformly high_order accurate Non
Oscillatory (UNO) schemes, which are based on characteristic variables and are applied to the fluxes
of the convected quantities directly, including mass flow rate. The developed scheme is applied to
the computation of steady transonic and supersonic flow over a bump in channel geometry for
various Mach number as well as to the transient shock tube problem. Also the results of steady
supersonic flow over a ramp are presented. Then the results are compared with data predicted by
TVD schemes based on characteristic variables.
