Numerical study for trihybrid nanomaterial flow by convectively heated curved sheet

Trihybrid nanofluid has vast applications including cooling systems, heat exchangers, electronic chips, automobile radiators, slurries, and biomedicine. Flow of MHD hybrid nanomaterial by convectively heated surface with entropy formulation is explored. The trihybrid nanofluid model is composed of three distinct nano-sized particles along with base material. Here 2 % of ferric oxide (Fe₃O₄), 2 % of silver (Ag) and 2 % of copper (Cu) nanoparticles are taken with ethylene glycol (C₂H₆O₂) as base fluid. Nonlinear differential system is constructed. Adequate transformation is employed in order to compute the problem numerically by applying the finite difference method. When compared to regular fluid, nanofluid and hybrid fluid, the trihybrid nanofluid exhibits superior thermal properties. It is perceived that adding nanoparticles in traditional fluids improve the ability to transmit heat. The temperature field and velocity are shown visually in relation to a number of emerging parameters. The coefficient of skin friction, Bejan number and rates of entropy and heat transfer have been explored physically. The results revealed that with magnetic effects the velocity field reduces while temperature improves when volume fraction for trihybrid nanoparticles is taken as 2 %. Moreover, the Bejan number is also improved by altering the radiation parameter. Excellent agreement is found when current numerical results for curved surfaces are compared to previous published literature for regular flat surface for large K.
