Abstract
AbstractHybrid finite compact (FC)‐WENO schemes are proposed for shock calculations. The two sub‐schemes (finite compact difference scheme and WENO scheme) are hybridized by means of the similar treatment as in ENO schemes. The hybrid schemes have the advantages of FC and WENO schemes. One is that they possess the merit of the finite compact difference scheme, which requires only bi‐diagonal matrix inversion and can apply the known high‐resolution flux to obtain high‐performance numerical flux function; another is that they have the high‐resolution property of WENO scheme for shock capturing. The numerical results show that FC‐WENO schemes have better resolution properties than both FC‐ENO schemes and WENO schemes. In addition, some comparisons of FC‐ENO and artificial compression method (ACM) filter scheme of Yee et al. are also given. Copyright © 2006 John Wiley & Sons, Ltd.
