Basic Study on Heat Transfer Enhancement in Straight Fins by Pulsating Flow
: Efficient thermal management is essential for high-heat-flux electronic devices, where increasing power density and compact packaging impose strict requirements on cooling performance with minimal pressure drop. Pulsating flow has been proposed as a technique to enhance heat transfer; however, its effects on practica...

Numerical Optimization of a Developed Multi-Baffle Heat Sink for Modern Electronic Devices
Optimal thermal control is crucial for ensuring the efficiency and stability of modern electronic devices. This paper analyzes four multi-barrier heat sink models using computational fluid dynamics (CFD) to optimize heat removal from a hot surface under constant convection. We analyzed the models under laminar flow con...

A CFD–Regression Surrogate Framework for Thermohydraulic Modeling of a Novel Plate Heat Exchanger
Plate heat exchangers are widely used in compact thermal systems, where heat-transfer enhancement must be balanced against hydraulic losses. This study develops a computational fluid dynamics (CFD) and regression-based surrogate framework for a novel plate heat exchanger (NPHE) under two working-fluid regimes. Three-di...
