The utilization of Fourier’s law of heat conduction provides the parabolic partial differential equation of thermal transport, which provides the information regarding thermal transport for the initial time, but during many practical applications, this theory is not applicable. Therefore, the utilization of modified heat flux model is to be used. This work discusses the utilization of non-Fourier heat flux model to investigate thermal performance of tri-hybrid nanoparticles mixture immersed in Carreau Yasuda material past over a Riga plate by using Hamilton Crosser and Yamada Ota models considering the variable thermos-physical characteristics. The phenomenon presenting the transport of momentum and energy are developed in the form of coupled partial differential equations, which are complex and then transformed into ordinary differential equations by using an appropriate transformation. The transformed equations have been tackled numerically via finite element scheme and the authenticity of obtained solution is shown with the help of comparative analysis of present results with those are available in open literature.

Present research deals with the study of time-dependent pulsatile MHD (Magnetohydrodynamics) hybrid nanofluid with entropy optimization and electrokinetic force in a channel. The current mathematical model is formulated as the [Formula: see text] blood (Casson fluid) hybrid nanofluids flow between the bottom and wavy top walls. The pulsatile flow is subjected to an inverse magnetic field of uniform force to study the effect of the resulting Lorenz force. Exact solutions for velocity, temperature, heat transfer rate, and streamlines are constructed by employing the perturbation approach to evaluate coupled nonlinear partial differential equations (PDEs). The velocity [Formula: see text] of the blood-based [Formula: see text] hybrid nanofluid increases with increasing values of the electro-osmotic parameter. The higher values of copper-gold nanoparticle volume fraction increase the entropy generation [Formula: see text]. This theoretical investigation helps estimate entropy in systems biology, which is used to treat cancer and improve the function of medical devices.

Current investigation emphasizes the evaluation of entropy in a porous medium of Williamson nanofluid (WNF) flow past an exponentially extending horizontal plate featuring Parabolic Trough Solar Collector (PTSC). Two kinds of nanofluids such as copper-methanol (Cu-MeOH) and alumina-methanol (Al2O3-MeOH) were tested, discussed and plotted graphically. The fabricated nanoparticles are studied using different techniques, including TDDFT/DMOl3 method as simulated and SEM measurements as an experimental method. The centroid lengths of the dimer are 3.02 Å, 3.27 Å, and 2.49 Å for (Cu-MeOH), (Al2O3-MeOH), and (Cu-MeOH-αAl-MOH), respectively. Adequate similarity transformations were applied to convert the partial differential equation (PDEs) into nonlinear ordinary differential equations (ODEs) with the corresponding boundary constraints. An enhancement in Brinkmann and Reynolds numbers increases the overall system entropy. WNF parameter enhances the heat rate in PTSC. The thermal efficiency gets elevated for Cu-MeOH than that of Al2O3-MeOH among 0.8% at least and 6.6% in maximum for varying parametric values.
