A Component-wise TVD Scheme in Numerical Simulation of Aerodynamics
-
摘要: 本文选取一个精度较高的TVD限制子,把著名的二阶Mac Cormack格式和Warming-Beam格式结合,构造了一种分量形式的二阶TVD差分格式。通过两个典型算例的计算,并与ENO格式的结果比较,显示了该格式精度高和计算逻辑简单的特点。Abstract: A component-wise TVD scheme,constructed with Mac Cormack scheme and Warming-Beam scheme,is achieved for numerical simulations of aerodynamics.Numerical results of two typical examples show its high accuracy and simple coding procedure.
