Control of entropy in algorithms and calculations of gas-dynamics flows
Based on one recently published approach, an analytical investigation of entropy behaviour in process of numerical integration of gas-dynamics equations is implemented. It confirms an existence of discontinuous solutions that similar to rarefaction shock-wave in numerical calculations. So, the postulate of non-increasing entropy is disturbed. Some simple methods to control of entropy in gas-dynamic flows and other known numerical methods are suggested.
