Abstract

The transport performance for a convective non-Newtonian fluid model with heat transfer can be measured through skin friction coefficient, and Nusselt number. The aim of this study is to examine the sensitivity analysis of heat transfer and drag forces effects on magnetized Reiner-Philippoff fluid model over curved surface. The equations that regulate the flow issue are converted into a set of nonlinear dimensionless partial differential equations via a non-similarity transformation. These equations are treated as ordinary differential equations by employing the local non-similarity method up to second level truncation and simulated using MATLAB routine bvp4c. Prior to doing the sensitivity analysis of skin friction coefficient, and Nusselt number, we use response surface methods to construct empirical connections for these parameters. The empirical relations' quality of fit is determined using the analysis of variance table's coefficient of determination. The results show that coefficient of determination for skin friction coefficient, and Nusselt number are 100 %, 99.99 % and 97.73 % respectively. This means that we have obtained best fitted empirical relations. The results of sensitivity analysis disclosed that skin friction coefficient is most sensitive to Reiner-Philippoff fluid parameter.

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.
