Hybrid Nano-Jet Impingement Cooling of Double Rotating Cylinders Immersed in Porous Medium

A cooling system with impinging jets is used extensively in diverse engineering applications, such as solar panels, electronic equipments, battery thermal management, textiles and drying applications. Over the years many methods have been offered to increase effectiveness of design by different techniques. In one available methods, nano-jets are achieve a higher local average heat transfer coefficient. this study, convective double rotating cylinders embedded porous medium analyzed using hybrid nano-jets. finite element formulation thermo-fluid considered, while impacts Reynolds number, rotational speed cylinders, permeability distance between on performance numerically assessed. Hybrid pure fluid performances jet compared. It observed that improves when cylinder, number increased. The behavior varying for first second cylinder. Higher achieved nanofluid nanoparticle loading used. An optimization algorithm finding optimum speeds obtaining an improved performance, results show compared parametric study. outcomes present work useful configurations encountered cooling, energy extraction waste recovery.
