A Study on the validity of Muzaferijal and Gosman’s Defer Correction Formula in the unstructured FVM

Abstract

   For analyzing the complex flow field such as urban space, Finite Volume Method (FVM) with the unstructured grid system is often used because of its’ high adaptability to complex geometry. In this study, the numerical accuracy of FVM with the unstructured grid system in respect of some mesh geometries is estimated and compared with that of Finite Differential Method (FDM). Especially, the validity of Muzaferijal and Gosman’s Defer Correction Formula in the unstructured FVM is evaluated. In this paper, the truncation errors when FVM with the unstructured grid system in respect of some mesh geometries is applied, is clarified and notation when Muzaferijal and Gosman’s Defer Correction Formula is used, is shown.
