Abstract

The presence of nanoparticles in the pure fluid can considerably improve the heat and mass transference properties of fluid. Such types of fluids have various applications in cooling systems, heat exchangers, and thermal management system where effectual heat transfer is essential. Therefore, in this analysis, we have examined the flow of a water-based hybrid nanofluid containing copper (Cu) and alumina (Al2O3) nanoparticles along with gyrotactic microorganisms on an elongated sheet. The analysis is done via the bvp4c MATLAB function in order to analyze the current model numerically by implementing convective boundary conditions. From the results obtained, we observed that greater magnetic fields and porous media decreased both primary and secondary velocities. It is detected that the greater ratio factor has a direct relation with the secondary velocity distribution while it has an indirect relation with the primary velocity distribution. The nanoparticle volume fraction distribution has been increased by the thermophoresis factor while reduced by the Schmidt number and Brownian motion factor. The greater magnetic, Brownian motion, heat source, thermal radiation factors, and thermophoresis factors have increased the heat transfer rate. The greater Schmidt number and Brownian motion factor have increased the Sherwood number while it has been reduced by the greater thermophoresis factor.

期刊介绍： Case Studies in Thermal Engineering provides a forum for the rapid publication of short, structured Case Studies in Thermal Engineering and related Short Communications. It provides an essential compendium of case studies for researchers and practitioners in the field of thermal engineering and others who are interested in aspects of thermal engineering cases that could affect other engineering processes. The journal not only publishes new and novel case studies, but also provides a forum for the publication of high quality descriptions of classic thermal engineering problems. The scope of the journal includes case studies of thermal engineering problems in components, devices and systems using existing experimental and numerical techniques in the areas of mechanical, aerospace, chemical, medical, thermal management for electronics, heat exchangers, regeneration, solar thermal energy, thermal storage, building energy conservation, and power generation. Case studies of thermal problems in other areas will also be considered.
