齋藤元浩0 (京都大学),吉田英生(京都大学) Numerical calculation of flow field by SIMPLE method with Excel Hiroshi IWAI, Yuki SUKIZAKI, Motohiro SAITO and Hideo YOSHIDA ABSTRACT It is convenient to use Excel spreadsheet for a numerical simulation, because we can get the visual results in real time. In particular, for beginners, the calculation supported with Excel is a good motivator and trainer. In the present study, we use the Excel for a numerical analysis of two-dimensional flow by SIMPLE (Semi-ImpUcit Method for Pressure Linked Equations). The first step is a discretization of basic equations in the. same way with general numerical simulations. Next, the discretized equations are embedded into Excel worksheets in which the iterative calculations are performed. We can apply this method to various shapes of channel easily compared with the conventional numerical calculations.
