Computational Assessment of Microrotation and Buoyancy Effects on the Stagnation Point Flow of Carreau–Yasuda Hybrid Nanofluid with Chemical Reaction Past a Convectively Heated Riga Plate

Abstract

The present framework deliberated the mixed convection stagnation point flow of a micropolar Carreau–Yasuda hybrid nanoliquid through the influence of the Darcy-Forchheimer parameter in porous media toward a convectively heated Riga plate. In this investigation, blood is used as a base liquid and gold (Au) and copper (Cu) are the nanoparticles. The main novelty of the present investigation is to discuss the transmission of heat through the application of thermal radiation, viscous dissipation, and the heat source/sink on the flow of a micropolar Carreau–Yasuda hybrid nanoliquid. Further, the results of the chemical reaction are utilized for the computation of mass transport. Brownian motion and thermophoretic phenomena are discussed in the current investigation. The current problem is evaluated by using the connective and partial slip conditions and is formulated on the basis of the higher-order nonlinear PDEs which are converted into highly nonlinear ODEs by exploiting the similarity replacement. In the methodology section, the homotopic analysis scheme is employed on these resulting ODEs for the analytical solution. In the discussion section, the results of the different flow parameters on the velocity, microrotation, energy, and mass of the hybrid nanofluid are computed against various flow parameters in a graphical form. Some of the main conclusions related to the present investigation are that the velocity profile is lowered but the temperature is augmented for both nanoparticles volume fractions. It is notable that the skin friction coefficient is reduced due to the higher values of the Darcy-Forchheimer parameter. Further, the rising performance of the hybrid nanofluid Nusselt number is determined by the radiation parameter.

Dual Solutions of Unsteady Mixed Convection Hybrid Nanofluid Flow Past a Vertical Riga Plate with Radiation Effect

“…In contrast, the heat transmission rate improved due to these parameters. Additional recent and intriguing studies on the mixed convection hybrid nanofluid flow over a Riga plate have also been mentioned (see Ahmad et al [47]; Alshehri et al [52]; Khashi'ie et al [53]; Nadeem et al [54]; Nayak et al [55]; Ramzan et al [56]; Salawu et al [57]; and Shatnawi et al [58]).…”

Numerical thermal study of ternary nanofluid influenced by thermal radiation towards convectively heated sinusoidal cylinder

“…They examined rapid movement of the fluid particle with enlarging curvature number and opponent behaviour observed for slip and magnetic forces effects. Ramzan et al [ 15 ] investigated the heating ability of Carreau-Yasuda nanofluid with chemical species and upthrust. The achieved model successfully solved via numerical approach and a detailed discussion provided with ranges of parameters.…”
