Effects of Arrhenius Activation Energy and Binary Chemical Reaction on Convective Flow of a Nanofluid over Frustum of a Cone with Convective Boundary Condition

Abstract

In this article, we investigate the effects of Arrhenius activation energy with binary chemical reaction and convective boundary condition on natural convective flow over vertical frustum of a cone in a Buongiorno nanofluid under the presence of thermal radiation. The zero nanoparticle flux condition is used at the surface of frustum of a cone rather than the uniform wall condition to execute physically applicable results. For this complex flow model, a suitable non-similarity transformations are used initially and then Bivariate pseudo-spectral local linearisation method is used to solve the non-similar, coupled partial differential equations. Further, the convergence test and error analysis are conducted to verify the accuracy of numerical method. The effects of flow influenced parameters on the non-dimensional velocity, temperature, nanoparticle volume fraction and regular concentration profiles as well as on the skin friction, heat transfer rate, nanoparticle and regular mass transfer rates are analyzed.

Impact of Activation Energy and Temperature-Dependent Heat Source/Sink on Maxwell–Sutterby Fluid

“…Nanofluid past a stretching sheet along with activation energy and convective boundary conditions was analyzed by Dhlamini et al [50] who found that the concentration distribution showed a decreasing trend in the case of improvement in the reaction rate constant parameter. Chetteti and Chukka [51] manipulated the consequences of activation energy and convective boundary conditions on nanofluid flow over a cone.…”

“…The boundary conditions are below, (see Ali and Sandeep [42]) and The governing equations for continuity, momentum, temperature, and concentration are below and are based on the assumptions stated above (see Vajravelu and Nayfeh [40], Chetteti and Chukka [41]).…”

Activation energy and binary chemical reaction on unsteady MHD Williamson nanofluid containing motile gyrotactic micro‐organisms

“…Abhas et al 2 studied the stagnation point of a Casson fluid by considering the binary chemical reaction. Chetteti and Chukka 3 examined the activation energy effect over a vertical frustum Buongiorno nanofluid. Khan et al 4 considered a stretched surface to investigate the impact of activation energy in a binary chemical reaction of Tio 2 ‐CuO‐H 2 O nanomaterials.…”
