Entropy generation on MHD Maxwell hybrid nanofluid over a Stretching cylinder with Cattaneo-Christov heat flux: Analytical and numerical simulations

Abstract

In the present study, we examine the influence of entropy generation on Maxwell hybrid nanofluid over a cylinder in the presence of non-linear thermal radiation and Cattaneo-Christov heat flux. In this model, we considered [Formula: see text] and [Formula: see text] are the nanoparticles which are suspended in the base fluid blood. The basic PDE’s (Partial differential equations) are transformed into ODE’s (Ordinary differential equations) by ensuring the suitable self-similarity transformations. ODEs are resolved using a Runge–Kutta 4th-order along with shooting procedure. Numerical method ( NM) and Homotopy perturbation method ( HPM) solutions for the nonlinear system are obtained so that they compared to each other for the case of cylinder. The HPM is developed for comparison purposes, and more accurate and reliable outcomes are illustrated through graphs. Moreover, the obtained results are compared with the existing literature and are found to be an excellent agreement. It is found that the fluid velocity reduces for the higher values of magnetic parameter. Higher values of the heat generation parameter improve the temperature profiles. Nusselt number decreases when developing Darcy–Forchheimer number and temperature time relaxation parameter. This type of flow problems may be utilized to improve the blood flow in the blood vessel has attracted the attention of physicians and biomedical researchers as it specializes in various treatments such as drug targeting, cell tissue engineering, cancer, hyperthermia and hypothermia.

MHD nonlinear thermally radiative Ag − TiO 2/H 2 O hybrid nanofluid flow over a stretching cylinder with Newtonian heating and activation energy

“…Hybrid nanofluids have diverse applications in heat exchangers, solar collectors, supercomputers, cancer therapy, heat pumps, photo-electric equipment, and geothermal power extraction. Many researchers have investigated the magnetohydrodynamic hybrid nanofluid flow over a stretching cylinder [6][7][8]. Patil and Kulkarni [9] have analyzed the mixed convective flow of Ag − TiO 2 /H 2 O hybrid nanofluid flow past a slender cylinder.…”
