Abstract
The investigation of the influence of Hall current (HC) on the flow of hybrid nanofluid (NF) over a curved stretchable surface (SS) is carried out. The mechanism of heat transfer is also analyzed by integrating the Joule heating (JH) effects and including the melting state of heat transfer. Ordinary differential equations (ODEs) of the current flow problem are obtained by utilizing the curvilinear coordinates system and some suitable similarity transformations. Numerical results of the formulated ODEs are attained by employing the shooting method. The impacts of assorted involved flow parameters like the radius of curvature, hybrid nanoparticles parameter, magnetic parameter, Prandtl number, melting heat parameter, and Eckert number on the flow, pressure, and temperature fields are shown in the figures. A comparison of results with a well-known finite difference based numerical scheme known as the Keller-box method is also presented. Also, the impacts of aforesaid parameters on surface friction and the heat transmission rate are explained through tables. It has been observed that the velocity profile, transverse velocity field, and pressure distribution are decaying with the magnetic parameter, whilst the temperature field is a growing function for the magnetic parameter.
