Abstract

The flow field in an enclosure with length to width ratio (L/B) of 2 and varying number of baffle plates (n) is computationally investigated. For each value of n the influence of the relative length of the baffle plate (ratio of length of the plate a to the width of the enclosure B, a/B ratio) on the flow field is investigated. Mainly the influence on the flow pattern is brought out. It is seen that by controlling the a/B ratio, the regions of recirculation, separation and stagnant zones can be controlled.
