Entropy Generation Analysis on MHD Ag+Cu/Blood Tangent Hyperbolic Hybrid Nanofluid Flow Over a Porous Plate

Abstract

This study is motivated by the vital role of dissipating thermal energy in the physiological system where energy depletion can lead to severe health complications. These complications encompass a range of issues, including sudden death, anemia, hypothermia, blood pressure fluctuations and the necessity for cardiac surgery. Biomedical engineers and clinicians have recognized the significance of analyzing entropy generation to quantify energy loss in biological systems. Furthermore, this study acknowledges the importance of understanding the thermodynamic state of entropy generation, particularly in evaluating cancer cells during chemotherapy treatment and enhancing heat transfer in tissues. The primary objective of this study is to evaluate the heat transfer characteristics of a magnetohydrodynamic (MHD) tangent hyperbolic hybrid nanofluid near a heat source and thermal radiation as it flows over a porous plate. The research methodology utilizes the MATLAB program bvp4c for solving the momentum and temperature equations. These equations are subsequently transformed into ordinary differential equations using the appropriate self-similarity variables. An elevation in the heat source parameter leads to heightened internal energy of liquid particles, resulting in an increase in temperature. Additionally, the magnetic field parameter is directly proportional to the entropy generation; as it increases, so does the entropy generation. Moreover, nanoparticles, owing to their high surface area-to-volume ratio, have the capacity to hinder heat transport within the fluid. The specific application of this study lies in the field of biomedical engineering and clinical practices. The findings can contribute to developing advanced heat-transfer techniques for medical applications, such as improving chemotherapy treatments for cancer cells and enhancing tissue heat-transfer efficiency. Moreover, using silver and copper nanoparticles as heat-transfer agents could hold promise in treating blood-related health conditions and facilitating the healing of injured tissue.
