Efficient heat transfer is critical for advancing thermal management systems across industries, yet traditional heat exchangers often underperform due to rigid designs and limited fluid dynamics. This study addresses this gap by investigating the use of elastic vortex generators and oscillating walls in pulsating channel flows, a novel approach with significant potential for enhancing heat transfer efficiency. The research aims to optimize heat transfer performance by exploring fluid-structure-thermal interactions in a two-dimensional channel with flexible, oscillating walls and fins. Using numerical simulations, the study evaluates the effects of pulsation parameters and elastic properties on turbulent flow and heat transfer. Key findings reveal that optimal configurations achieve up to a 13% increase in the Nusselt number, demonstrating superior heat transfer compared to conventional designs. However, excessive proximity between oscillating walls and vortex generators is shown to disrupt vortex formation, reducing efficiency. These results underscore the potential of flexible structures in revolutionizing heat exchanger designs for applications in energy systems, aerospace, and automotive cooling, offering a pathway to more efficient thermal management solutions.
