This numerical investigation effectively establishes a unique computing exploration for steady magnetohydrodynamic convective streams of tangent hyperbolic nanofluid traveling across a nonlinearly elongating elastic surface with a variable thickness. In addition, the importance of an externally imposed magnetic field of tangent hyperbolic nanofluid is comprehensively analyzed by considering the substantial impact of thermal conductivity and thermal radiation consequences. The governing PDEs (partial differential equations) are transmuted into a nonlinear differential structure of coupled ODEs (ordinary differential equations) using a series of variable similarity transformations. Furthermore, these generated ODEs (ordinary differential equations) are numerically set using a novel revolutionary Runge-Kutta algorithm with a shooting approach constructed in a MATLAB script. In this regard, extensive comparison studies are carried out to validate the acquired numerical results. The interactions between the associated profiles and the relevant parameters are rationally explored and shown using graphs and tabular forms. The velocity distribution declined with improving Weissengberg number We and power-law index m, while the reverse performance can be observed for temperature. As enhancement in Brownian motion, Thermophoretic and radiation parameters significantly rise in temperature distribution. The use of many different technological and industrial systems, including nano-bioconvective systems, nano-droplet evaporation, nano-ink jet printing, and microbial fuel cells, would benefit this research study.

“…Ahmad et al [30] used the Cattaneo-Christov heat flux model to investigate the unsteady bioconvective hybridised micropolar nanofluid flow across a vertical exponentially extending surface. Several scholars [31][32][33][34] recently investigated diverse fluid flows by adding the Cattaneo-Christov heat flux model into the energy equation.…”

This study compares the dynamics of dissipative water–alumina–zinc oxide–iron (II, III) oxide ternary hybrid nanofluid (THNF) and water–alumina–zinc oxide binary hybrid nanofluid flows across an inclined surface when quadratic thermal radiation and chemical reaction are important. This report presents the governing equations for the transportation of both dynamics using the thermo‐physical properties of water (base fluid), alumina nanoparticles, zinc oxide nanoparticles and iron (II, III) oxide nanoparticles. To analyse heat transmission phenomena, the Cattaneo–Christov heat flux model was added into the energy equation. With proper similarity transformations, flow‐driven equations are transformed into nonlinear ordinary differential equations and then solved using the bvp4c solver. Slope of linear regression (SLR) is used to determine the rate at which physical parameters increase or decrease as a result of the influence of relevant factors. It is noticed that, when volume percent of nanoparticles (ϕ1) takes input in the range 0≤ϕ1≤0.3$0 \le {\phi _1} \le 0.3$, skin friction coefficient decreases at a rate of 16.548 (in case of THNF) and 14.2018 (in case of binary hybrid nanofluid) per unit value of volume percent of nanoparticles. It is detected that when radiation parameter false(Rdfalse)$( {{R_d}} )$ increases, Nusselt number decreases. The decrement rates are observed as 2.9451 (in case of THNF) and 1.15337 (in case of binary hybrid nanofluid) when radiation parameter takes input in the range 0≤Rd≤0.3$0 \le {R_d} \le 0.3$. Furthermore, it is noticed that, when chemical reaction parameter false(Krfalse)$( {{K_r}} )$ increases, Sherwood number increases. The increment rates are observed as 0.1259 (in case of THNF) and 1.1263 (in case of binary hybrid nanofluid) when chemical reaction parameter takes input in the range 0≤Kr≤0.3$0 \le {K_r} \le 0.3$. There was also good agreement in a validation study between the current and previous results.

“…These changes in the density may also be caused by gradients in fluid composition or by difference in temperature and concentration distributions which is renowned as thermosolutal convection. It has received immense attention experimentally and theoretically due to superb existence in different frameworks [1][2][3][4][5][6][7][8][9][10][11]. In view of superb utilizations Beghein et al [12] probed thermosolutal diffusive phenomenon in air subjected to assisting or opposing associated gradients.…”
