Description
Summary:碩士 === 國立成功大學 === 化學工程學系 === 86 === The applicability and accuracy of differential cubature method (DCM) are investigated by solving several heat transfer problems in rectangular domain. In addition, problems in irregular domains are also analyzed by DCM in conjunction with the concepts of domain decomposition as well as master elements adapted from the finite element method. It is found that good results can usually be obtained by DCM. In addition, the accuracy of DCM can strongly influenced by the distribution of the grid points (nodes) . However, under similar grid-point distribution, small L2norm errors can usually be achieved by DCM than those obtained by finite difference method (FDM) and differential quadrature method (DQM). Investigations on the determination of optimum grid-point distribution in DCM shall be conducted in further studies.
