NUMERICAL VISUALIZATION OF FLOW INSIDE INTERSECTING DUCTS
SINOPSIS
A novel type of heat exchanger with high potential industrial applications is a flow network consisting of mutually intersecting holes in a plate. A series of empirical studies have been conducted to investigate fluid flow behavior in both a prototype unit and models using various flow visualization methods, such as hydrogen bubble, dye injection, string, particle methods, and laser Doppler velocimetry.
In this article flows in a pair of intersecting ducts with different intersection angles are investigated numerically using commercial software called Fluent. The Renormalization Group (RNG) k-ε model is used to simulate turbulence behavior in the flow.
The numerical visualization technique has successfully revealed turbulent flow characteristics inside the crossing ducts of various intersection angles. The formation of a flow divider and the presence of flow separation regions seen in experiments are confirmed. Three types of pressure-intersection angle relationships are found in different ranges of the intersection angles.
