TITLE: Design of Heat Exchangers for waste heat recovery
Abstract
Recovering waste heat from industrial processes is a key strategy for improving energy efficiency and reducing environmental impact. Heat exchangers play a central role in this process by transferring thermal energy from hot exhaust streams to useful applications such as heating, power generation, or preheating other process fluids. The effectiveness of a heat exchanger depends on several design parameters, including surface area, flow arrangement, temperature gradients, pressure drop, and material selection. Enhancing heat transfer while minimizing pressure loss remains a major challenge in heat exchanger design. One promising solution is the use of passive flow enhancement techniques, such as delta winglets, which generate longitudinal vortices that disrupt the thermal boundary layer and enhance convective heat transfer. These winglets improve flow mixing and increase the effective heat transfer coefficient without the need for additional power input. Integrating such features into heat exchanger channels can significantly improve the thermal performance and overall efficiency of waste heat recovery systems
