The thermal difficulties encountered in modern electronic equipment can be solved by using nanofluids, which reconcile the issues by designing an optimum structure for systems in refrigeration or improving heat transferal features. Numerical solutions reveal the existence of multiple solutions under certain parameters and a unique solution under others. Additionally, the presence of radiation, magnetic field, and hybrid nanoparticles can enhance thermal performance.
The equipment in the modern electronic frequently encounters difficulties in thermal significance due to a decline in effective surface area for heat exclusion or improved heat production. This most intriguing problem can be solved by designing an optimum structure for systems in refrigeration or improving heat transferal features. Therefore, nanofluid performs well enough in reconciling these issues. The goal of the current exploration is to theoretically inspect the steady magneto nanofluid flow with radiative heat transfer caused by a shrinking cylinder by employing the Tiwari-Das model. The radiation, suction, and magnetic parameters effects are investigated. The governing equations are converted to similarity equations by the similarity transformations. Later, for dissimilar values of the pertaining parameters, these equations are solved numerically by employing Matlab's function bvp4c. Outcomes perceived that the shrinking case gives the dual (multiple) solutions, and the unique solution is found for the stretching case. Moreover, the thermal performance is improved in the presence of radiation, magnetic field, and hybrid nanoparticles. It is found that the heat transfer rate is boosted up to 2.06% for CoFe2O4/water nanofluid. It is intensified when hybrid nanoparticles are considered with 4.23% increment compared to the regular fluid case. (C) 2022 Elsevier B.V. All rights reserved.
