An explicit characteristic-based finite volume method (CFVM) for solving two-dimensional scalar convection-diffusion equations is presented. The time-dependent convection-diffusion equation is derived from characteristic coordinates using the characteristic-based scheme, while the finite volume method is employed for deriving the discretized equations. Robustness and accuracy of the method have been evaluated by pure-convection, and convection-dominated diffusion problems. Numerical test cases have shown that the method provides good computational stability and can capture high-gradient solutions.View full textDownload full textKeywordsconvection-diffusion equation, characteristic-based scheme, finite volume methodRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/02533839.2011.565589
