32 加熱円柱・円柱列周囲の流れの数値計算

It is investigated to predict heat transfer and to visualize air flows around a cylinder and a single row of cylinders. Direct numerical simulation of Boussinesq approximated NavierStokes equation is carried, and upwind finite defference method with third order accuracy is used. Generalized cordinate system is adopted to give flexibility on treating objects to calculate.The results of calculations are visualized on a computer graphic display and made into animations. The results are successfully coincident with experiments, and some visualizations of the air flows are shown in this report.
