Mathematical modeling of thermal transfer in a symmetric peristaltic flow of a Newtonian fluid through a curved duct with entropy generation: a microfluidics application

Several different industries and disciplines can benefit from heat transfer in peristaltic flow in curved ducts, including biomedical engineering, industrial processes, microfluidics etc. In this study, the thermal aspects of peristaltic flow are thoroughly examined, with a particular focus on the impact of entropy generation in a symmetric curved duct. Notably, the curvature of the duct introduces additional complexity, enhancing the significance of this research. The resulting system of equations is then analytically solved using homotopy perturbation method (HPM). It is observed that fluid's temperature is increasing directly with aspect ratio but amplitude ratio and curvature exhibit inverse impact on it. It is also evaluated that the fluid's peristaltic pressure is enhanced by large curvature. The obtained results offer valuable guidance for designing and optimizing peristaltic systems in a wide range of applications, including biomedical devices, industrial processes, and microfluidic systems.
