自从电击捕捉方法发展以来，几乎所有目前可用的接触保存方法都会产生虚假的解决方案，据报道，碳现象是一种虚假的解决方案。目前的分析表明，碳现象的发生实际上与激波的数值结构有很大的关系。比较了基于矩阵的稳定性分析和欧拉有限体积计算，以说明内激波结构对触发碳化现象的重要性。版权所有©2005 John Wiley&Sons，Ltd.
Since the development of shock‐capturing methods, the carbuncle phenomenon has been reported to be a spurious solution produced by almost all currently available contact‐preserving methods. The present analysis indicates that the onset of carbuncle phenomenon is actually strongly related to the shock wave numerical structure. A matrix‐based stability analysis as well as Euler finite volume computations are compared to illustrate the importance of the internal shock structure to trigger the carbuncle phenomenon.
