TITLE: Passive Flow Control Using Slotted Wall-Mounted Bluff Bodies
Abstract
The increasing power density of electric vehicles and compact electronic systems requires efficient thermal management solutions that enhance cooling while minimizing energy consumption. This research investigates passive flow control using slotted wall-mounted bluff bodies to improve convective heat transfer and flow stability. High-fidelity computational fluid dynamics simulations, including the Improved Delayed Detached Eddy Simulation and Volume of Fluid methods, are used to examine the effects of slot geometry on wake dynamics, turbulence generation, and thermal performance. Parametric studies are conducted to evaluate the influence of slot type, orientation, and flow conditions on heat transfer enhancement and vortex suppression. Numerical results are validated using particle image velocimetry measurements. Advanced flow analysis techniques are employed to characterize coherent flow structures and turbulence mechanisms responsible for enhanced cooling. The study establishes relationships between slot geometry, wake behavior, and thermal performance, providing design guidelines for compact and energy-efficient cooling systems for electric vehicles and electronic devices.
