Bio-convection in tri-hybrid nanofluid flow with Arrhenius activation energy: Incorporating the Cattaneo-Christov heat flux model

Abstract

The recent study is related to Cattaneo-Christov model of Electromagnetohydrodynamic (EMHD) tri-hybrid nanofluid flow in the occurrence of gyrotactic microorganisms, heat source/sink, Arrhenius activation energy, chemical reaction, natural convection, and thermal radiation on two dissimilar geometries i.e., wedge and cone. The tri-hybrid nanofluid flow with Electromagnetohydrodynamic (EMHD) has many uses in industrial and engineering fields. Most medicinal and organic uses require a study into the insight process in nanofluid consisting of microorganism suspension. The system of partial differential equations is changed into a set of ordinary differential equations by using similarity transformation. The semi-analytical technique HAM is used to attain the solution to the problem. The influence of substantial constraints on temperature, velocity, motile density microorganisms, and concentration, are displayed through graphs. Velocity of tri-hybrid nanofluid (THNF) is increased for rising in electric parameter. Results show that the velocity of THNF rises by approximately 8.5% with a rise in the electric parameter $E_1$ = 0.1  →  0.4. The temperature profile rises by approximately 10% with a rise in the magnetic parameter $M$ = 0.5  →  2.0 and by about 7% for an upsurge in the electric parameter $E_1$ = 0.1  →  0.4. The concentration profile reduces by approximately 9% with a rise in the Arrhenius activation parameter $E_2$ = 0.2  →  0.8. The motile microorganism density diminishes by nearly 11% for growing Peclet number $P_e$ = 0.3  →  1.0 and by 8% with a greater bio-convection Lewis number $L_b$ = 0.5  →  0.8. The numerical outcomes of local density number, Nusselt number, Sherwood number, and skin friction are shown in the tables. The addition of silver, copper and aluminum oxide increases the thermal physical behavior of the base fluid considerably.
