Paper Abstract

A flow in the combustion chamber of an engine is very complicated and it is very important to grasp the flow field for the design of the chamber. This study deals withthevisualization of the transient pattern of the air flowing in the combustion chamber and the observation of the effect of the difference in the combustion chamber's shapes. For the flow visualization, a new spark and radiant particle combustion method has been developed. In this method, particles are dispersed in the flow to be measured and in the spark discharge they generate radiant trails that show the flow direction. Using this method, the flow patterns, which clearly show the flow direction, are obtained. In these results, little differences are seen according to the shapes. And a flow rolling up from outward to the center is clearly recognized from the flow patterns.
