Abstract
Transformers are basically used to transform electric power into a user manual. Many types of transformers are being used for boosting electricity for several purposes. On using transformers, its windings produces heat due to convective heat transfer in the base oil and causes damage to its inner parts. This heat production in different parts of transformers is a complex engineering problem to be reported. To overcome heat production and to increase heat conductivity of the base oil some well-known nano particles are used. In this article, Casson fluid is considered as transformer base oil with WO<inf>3</inf> nano particles, as Casson fluids non-Newtonian behaviour enhances heat transfer, allowing more efficient cooling of transformers. Due to its high dielectric strength makes it attractive to traditional transformers oil. It is observed that by adding WO<inf>3</inf> nano particles transformer oil based Casson fluid, heat conduction can be improved up to 6.741% as compared to base oil without nano particles. This problem has been modelled by means of Caputo–Fabrizio fractional approach and then solved using the Laplace and Hankel transformation. Effect of various embedded parameters like Grashoff, Prandtl, and magnetic parameters have been discussed physically and graphically for thermal conductivity of transformers oil and also Nusselt number is tabulated to check ratio of conduction and convection in the transformer and based oil. Moreover, increases the volume fraction of WO<inf>3</inf> nanoparticles increase the heat production within the working fluid transformer oil.
