A new algorithm was proposed to calculate the weights of sub-schemes in hybrid compactWENO( weighted essentially non-oscillatory) schemes. It used smoothness indicators of the stencils of hybrid schemes as variables to work globally. The new weight algorithm employed none freely user-defined parameter,making the hybrid schemes more robust and applicable. Two different 5th order upwind compact schemes were coupled with a 5th order WENO-Z scheme respectively. The new algorithm maked the transition between two...
