摘要：

The study of heat and mass transmission characteristics of fluid flow over rotating surfaces has many engineering and industrial applications. It forced researchers to conduct further theoretical and experimental studies on it throughout the last century. Sequel to the significance of forced convection flow on convectively surfaces, nothing is known on forced convection flow of a Newtonian fluid between co-rotating and stretchable disks with emphasis on the significance of Reynold number, Lorentz force, mass flux due to gradient in heat energy. The present study examines the convective fluid flow of co-rotating stretchable disks. A vertical magnetic field is incorporated in the flow while the energy equation is modeled, taking the Dufour and Soret effects as heat generation through viscous dissipation and ohmic heating plays a vital role in designing various engineering devices such as electric stoves, heaters, thermistors, food processing, etc. The resulting system after using suitable transformations is numerically solved using the BVP Midrich scheme in Maple software. The impact of incorporated pertinent parameters on velocity, concentration, and temperature profiles are studied numerically. It is observed that magnetic field, Dufour, and Soret parameter enhance Nusselt number at the lower disk while declining with Reynolds number. The reverse trend is watched in the Sherwood number for the said parameters as described before. The current model is calibrated by comparing it with the existing literature, and good agreement is found. © 2022, The Author(s), under exclusive licence to Springer Nature India Private Limited.
