A New Reconstruction Technique for the Euler Equations of Gas Dynamics with Source Terms,terms. This method introduces modified conserved variables that can be used in any high-order reconstruction process and which contain information about the source terms. By using these variables, modified slopes are obtained and a robust and accurate reconstruction procedure is formulated. Applicat作者: 滲入 時(shí)間: 2025-3-22 16:47
