Numerical Solution of Incompressible Flows by Discrete Singular Convolution

International Journal for Numerical Methods in Fluids, 2002
AbstractA discrete singular convolution (DSC) solver is developed for treating incompressible flows. Three different two‐dimensional benchmark problems, the Taylor problem, the driven cavity flow, and a periodic shear layer flow, are utilized to test the accuracy, to explore the reliability and to demonstrate the efficiency of the present approach ...

Vibration Analysis of Conical Panels Using the Method of Discrete Singular Convolution

Communications in Numerical Methods in Engineering, 2006
AbstractA discrete singular convolution (DSC) free vibration analysis of conical panels is presented. Regularized Shannon's delta kernel (RSK) is selected as singular convolution to illustrate the present algorithm. In the proposed approach, the derivatives in both the governing equations and the boundary conditions are discretized by the method of DSC.

Discrete Singular Convolution Method for the Analysis of Mindlin Plates on Elastic Foundations

International Journal of Pressure Vessels and Piping, 2007
The method of discrete singular convolution (DSC) is used for the bending analysis of Mindlin plates on two-parameter elastic foundations for the first time. Two different realizations of singular kernels, such as the regularized Shannon's delta (RSD) kernel and Lagrange delta sequence (LDS) kernel, are selected as singular convolution to illustrate ...
