Coupled Impression of Radiative Thermal Flux and Lorentz Force on the Water Carrying Composite Nanoliquid Streaming Past an Elastic Sheet

Significance of the study: Hybrid nanofluids attract the attention of many current researchers due to the enhanced heat transport rate in many engineering and industrial applications. The influence of an inclined magnetic field over an exponentially stretched sheet in the presence of thermal radiation cannot be ignored and the literature available in this domain is scanty. The novelty of this communication is to explore the impact of inclined magnetic field and thermal radiative heat on the hybrid nanofluid consisting of and nanoparticles in the base fluid, water. Aim of the study: A mathematical model for hybrid nanofluid is proposed to study the influence of oblique magnetic field and thermal radiation on an exponentially elongated sheet. A comparision of the thermal characteristics of the hybrid nanofluid and the mono nanofluids is made. Research methodology: The governing flow equations are transformed into a system of ODEs with the assistance of similarity variables and are then computationally addressed using bvp4c.The graphs are displayed for velocity, heat measure and reduced frictional coefficients for selected flow parameters. Results: Hybrid nanofluid has 1-4 % growth in the rate of heat transfer when compared to mono nanofluid while it is 1-4.5% in comparison to viscous fluid for increasing radiation parameter. Conclusion: The outcomes of this work revealed that the heat transfer as a consequence of the dispersion of dual nanomaterials is more promising than the mono nanofluid. To accomplish very effective cooling/ heating in industrial and engineering applications, hybrid nanofluids can substitute mono nanofluids.
