Abstract
An alternative method for the solutions of compressible, rotational, transonic flows has been presented. The method can also be regarded as a natural zonal decomposition technique without switching the formulation between zones of different physics. In the approach, local physics are accommodated by the control of convective quantities, without drawing zonal boundaries for different physics.
The four test cases verified the applicability of the proposed method in two-dimensions, and compared to the conventional Euler and full potential technologies. The Clebsch Euler formulation solves for each variable by following individual characteristics, which distinguishes the present approach from the conventional Euler method. The proposed technology is directly extensible to three dimensional flows. Further research is desirable to extend the method into viscous flow problems.
