Motivated by emerging high-temperature manufacturing processes deploying nano-polymeric coatings, the present study investigates nonlinear thermally radiative Oldroyd-B viscoelastic nanoliquid stagnant-point flow from a heated vertical stretching permeable surface. Robin (mixed derivative) conditions were utilized in order to better represent coating fabrication conditions. The nanoliquid analysis was based on Buongiorno’s two-component model, which features Brownian movement and thermophoretic attributes. Nonlinear buoyancy force and thermal radiation formulations are included. Chemical reactions (constructive and destructive) were also considered since coating synthesis often features reactive transport phenomena. An ordinary differential equation model was derived from the primitive partial differential boundary value problem using a similarity approach. The analytical solutions were achieved by employing a homotopy analysis scheme. The influence of the emerging dimensionless quantities on the transport characteristics was comprehensively explained using appropriate data. The obtained analytical outcomes were compared with the literature and good correlation was achieved. The computations show that the velocity profile was diminished with an increasing relaxation parameter, whereas it was enhanced when the retardation parameter was increased. A larger thermophoresis parameter induces an increase in temperature and concentration. The heat and mass transfer rates at the wall were increased with incremental increases in the temperature ratio and first order chemical reaction parameters, whereas contrary effects were observed for larger thermophoresis, fluid relaxation and Brownian motion parameters. The simulations can be applied to the stagnated nano-polymeric coating of micromachines, robotic components and sensors.

We consider the Casson hybrid nanofluid (HN) (ZnO + Ag/Casson fluid) that flows steadily along a two-directional stretchable sheet under the influence of an applied changing magnetic flux and is electrically conducting. The basic Casson and Cattaneo− Christov double diffusion (CCDD) formulations are used for the simulation of the problem. This is the first study on the analysis of the Casson hybrid nanofluid by using the CCDD model. The use of these models generalize basic Fick's and Fourier's laws. The current produced due to the magnetic parameter is taken into consideration by using the generalized Oham law. The problem is formulated and then transformed to a coupled set of ordinary differential equations. The simplified set of equations is solved using the homotopy analysis method. The obtained results are presented through tables and graphs for various state variables. A comparative survey in all the graphs is presented for the nanofluid (ZnO/Casson fluid) with the HN (ZnO + Ag/Casson fluid). These graphs depict the effect of various pertinent parameters, like Pr, M, Sc, γ, Nt, m, Nb, δ 1 , and δ 2 , varying values over the flow. The Hall current parameter m and stretching ratio parameter γ show increasing trends for the velocity gradient, while the magnetic parameter and the flux of mass depict opposite trends for the same profile. The increasing values of the relaxation coefficients show an opposite trend. Furthermore, the ZnO + Ag/Casson fluid shows a good performance in the transfer of heat and thus can be used for cooling purposes to increase the efficiency of the system.

The industry level enhancement of the thermal conductivities of various base fluids is greatly aided by a nanofluid. Most engineering phenomena call for the removal of heat in order to improve industrial machinery performance. These fluids have a variety of uses, such as coolants for electric gadgets, car engines, heat exchangers and nuclear reactors. In this article, the authors have investigated the micropolar water‐based hybrid nanofluid containing silver and alumina nanoparticles over an extending surface. The flow problem also takes into account the Joule heating, variable heat source/sink, thermal radiation, chemical reaction, and activation energy. The flow problem is taken in the form of PDEs which are then transformed to ODEs by means of suitable similarity variables. The flow problem is solved with the help of HAM, which is capable of solving highly nonlinear partial and ordinary differential equations. The convergence of the HAM is also shown with the help of Figure 1. The results showed that the physical parameters have a greater influence on the velocity profile of nanofluid flow than hybrid nanofluid flow. However, the upshots of the physical constraints on the thermal profiles have a dominant impact on the hybrid nanoliquid flow relative to nanofluid. Also, it found that the physical parameters have a greater influence on the energy and mass transfer rates of the hybrid nanofluid flow than the nanofluid.
