INCOMPRESSIBLE FLOW THROUGH MULTIPLE PASSAGES

Abstract

In this paper, numerical simulations of incompressible flow through complicated multiple-flow passages in a container are shown. Several arrangements of multiple passages are examined. The whole region is divided into several zones for easy treatment of complicated geometry. The calculation is conducted in each zone, the results of which are connected at each boundary during calculation. An experiment was also conducted for one case to verify the calculated result. At least the qualitative agreement with experiment is good for the flow rate through each passage. The pressure distributions are also calculated, which show reasonable results. Furthermore, the thermal calculation in forced convection flow was performed for one case. Finally, an interesting flow pattern is obtained in a bifurcated channel problem along with each flow rate.
