Use of a characteristic surfaces for unsymmetrical supersonic flow problems /

Application of the method of characteristics to the linearized three-dimensional equation results in a relatively simple system of difference equations that can be used to compute the supersonic flow past boundaries for which no other linearized solutions are available.The three-dimensional nonlinear partial differential equation for the velocity potential in a supersonic stream is transformed by the method of characteristics to a system of three difference equations. Use of the difference equations for computing the supersonic potential flow past unsymmetrical boundaries is discussed.NACA TN No. 1849."March 1949."Includes bibliographical references.Application of the method of characteristics to the linearized three-dimensional equation results in a relatively simple system of difference equations that can be used to compute the supersonic flow past boundaries for which no other linearized solutions are available.The three-dimensional nonlinear partial differential equation for the velocity potential in a supersonic stream is transformed by the method of characteristics to a system of three difference equations.
