TURBULENT MULTI-BRANCHING RADIAL SYMMETRIC FLOW STRUCTURES

Abstract

This study builds upon previous research that developed optimized tree-shaped flow networks within disc-shaped bodies for enhanced thermal management, extending these principles to explore turbulent flow regimes. Previously, a multi-branching approach combined with strategic hydraulic diameter settings was utilized to balance thermal and fluid performance in laminar flow conditions, successfully minimizing flow resistance. These efforts revealed that symmetric tree designs could significantly boost hydraulic and thermal efficiencies via a constrained minimization approach. In the current work, the focus shifts to examining the implications of transitioning these optimized designs from laminar to turbulent flow conditions. By comparing performance metrics between the two regimes, this study aims to elucidate the effects of flow regime transitions on network efficiency and effectiveness. The results enhance understanding of the fundamental dynamics governing flow networks and guide the development of more robust designs capable of operating across a broader range of flow conditions.
