Abstract
Thermal heat generation and enhancement have been examined extensively over the past two decades, and nanofluid technology has been explored to address this issue. In the present study, we discuss the thermal heat coefficient under the influence of a rotating magneto-hydrodynamic hybrid nanofluid over an axially spinning cone for a prescribed wall temperature (PWT) case. The governing equations of the formulated problem are derived by utilizing the Rivlin–Ericksen tensor and boundary layer approximation (BLA). We introduce our suppositions to transform the highly non-linear partial differential equations into ordinary differential equations. The numerical outcomes of the problem are drafted in MATLAB with the of help the boundary value problem algorithm. The influences of several study parameters are obtained to demonstrate and analyze the magneto-hydrodynamic flow characteristics. The heat and mass transfer coefficients increase and high Nusselt and Sherwood numbers are obtained with reduced skin coefficients for the analyzed composite nanoparticles. The analyzed hybrid nanofluid (SWCNT-Ag–kerosene oil) produces reduced drag and lift coefficients and high thermal heat rates when compared with a recent study for SWCNT-MWCNT–kerosene oil hybrid nanofluid. Maximum Nusselt (Nu) and Sherwood (Sh) numbers are observed under a high rotational flow ratio and pressure gradient. Based on the results of this study, we recommend more frequent use of the examined hybrid nanofluid.

Summary
Introduction published maps and institutional affilProgress in the growth of technologies describing the behavior of fluid flows over a cone or through a cone has increased vastly. The practical applications of this particular phenomenon have importance and applications in industries such as engineering, dental health, paper production, and solar power collection. The generation and absorption of heat with unsteadiness inflow over a cone can be applied in many engineering fields, such as in the petroleum industry, pharmaceutical processing, environment control, solar pumps, and plantations. Major industrial applications utilize hybrid nanofluids, such as in parabolic trough collectors, solar energy, food processing, and drug delivery [1–5]. Anilkumar and Roy discussed the mixed convection of unsteady flow over a rotating cone [6]. Hussain et al [7] explored heat transportation over a rotating cone in MHD flow over a radiation regime with hybrid nanofluids. Nadeem and Saleem [8] studied magnetohydrodynamic flow over a rotating cone for time-dependent mixed convection.
