Abstract

This paper presents a biased-flux method based on an explicit finite-volume formulation for the solution of the Euler equations. This method uses an upwind or downwind bias in the flux calculation for various flow variables, according to the subsonic or supersonic character of the local flow. As a result, in this method there is no need for artificial dissipation for locally subsonic or supersonic flows, which substantially increases the computational efficiency. The solutions obtained with this method for quasi 1-D nozzle flows and for subsonic, transonic and supersonic 2-D flows in nozzles and past aerofoils were found in good agreement with previous results; in these typical tests, this method displayed an excellent computational efficiency
