| Abstract: | A new method called the flux vector splitting method is proposed to calculate the gas liquid two phase transient flow. The flux vectors in the mass, momentum and energy equations are split into flux subvectors according to the Jacobian matrix. The finite difference equations are formulated using the upwind format. The method is found to be stable and is capable of automatically and accurately capturing the shock wave. |
