Abstract: | This paper presents the results of using high-order compact schemes with a high-order filter on multi-block domains. The Linearized Euler Equations (LEE) are solved on a uniform mesh for benchmark problems in one and two dimensions. Also a two dimensional mixing layer is solved by using Large-Eddy Simulation (LES). Three different boundary schemes are compared. The results compare well with the exact solutions and single-block domain results. The effect of the number of points of overlap among the subdomains is investigated. Having four points of overlap is chosen as a compromise between accuracy and efficiency. |
