摘要: IN HYPERSONIC flow computations, it is a key issue to predict surface heating accurately. However, it is still challenging to compute hypersonic flows, because there are always possibilities of resulting in anomalous¶(unstable or oscillatory) solutions (Fig. 1). The most notorious example is the carbuncle phenomenon first reported by Peery and Imlay [1]. The carbuncle is a shock-induced instability and such anomalies appear depending on the following factors and their combinations [2, 3]: flow conditions (Mach number, Reynolds …
