Generalized differential quadrature analysis of unsteady three‐dimensional MHD radiating dissipative Casson fluid conveying tiny particles

The characteristics of three-dimensional stagnation point flow of Hybrid nanofluid past a circular cylinder are explored. The fluid flow is entertained in the presence/absence of thermal slip effects. The flow model is controlled through the partial differential equations. Since these equations are highly non-linear in character. So for the order reduction a suitable set of transformation is used. The reduced system is solved by using shooting method. The obtained results are offered through graphs and tables. It is noticed that the heat transfer rate is high in Hybrid nanofluid as compared to nanofluid. The present work is validated by developing comprising with existing literature.

Purpose




The purpose of this paper is to explore the effects of binary chemical reaction and activation energy on nano Casson liquid flow past a stretched plate with non-linear radiative heat, and also, the effect of a novel exponential space-dependent heat source (ESHS) aspect along with thermal-dependent heat source (THS) effect in the analysis of heat transfer in nanofluid. Comparative analysis is carried out between the flows with linear radiative heat process and non-linear radiative heat process.




Design/methodology/approach




A similarity transformation technique is utilised to access the ODEs from the governed PDEs. The manipulation of subsequent non-linear equations is carried out by a well-known numerical approach called Runge–Kutta–Fehlberg scheme. Obtained solutions are briefly discussed with the help of graphical and tabular illustrations.




Findings




The effects of various physical parameters on temperature, nanoparticles volume fraction and velocity fields within the boundary layer are discussed for two different flow situations, namely, flow with linear radiative heat and flow with non-linear radiative heat. It is found that an irregular heat source/sink (ESHS and THS) and non-linear solar radiation play a vital role in the enhancement of the temperature distributions.




Originality/value




The problem is relatively original to study the effects of activation energy and binary chemical reaction along with a novel exponential space-based heat source on laminar boundary flow past a stretched plate in the presence of non-linear Rosseland radiative heat.

Exploration of activation energy and binary chemical reaction effects on nano Casson fluid flow with thermal and exponential space-based heat source

Numerical communication for MHD thermally stratified dual convection flow of Casson fluid yields by stretching cylinder

The article reports analysis on magnetized Cross fluid flow along with the Joule heating effect over a radially stretching surface. The flow narrating mathematical model is obtained in terms of coupled partial differential equations. By utilizing the boundary layer theory the active part of system is retained and by applying the suitable transformations we achieved the dimensionless mathematical system. Both the transformed momentum and energy equations are solved with the help of shooting method. The impact of involved parameters are examined. The quantity of interest in this direction includes the velocity and temperature profiles of Cross fluid. It is noticed that the Cross fluid velocity decreases towards positive values of Weissenberg number, Power law index and magnetic field parameter. The thermal boundary shows an uplift for increment in Eckert number, and heat generation parameter, while the decline nature is observed in Cross fluid temperature against positive values of both the heat absorption parameter and magnetic field parameter. The surface quantity namely, the local skin friction increases with the increment of Weissenberg number whereas, it reflects opposite results for the Power law index. The obtained results are validated by developing comparison with existing results which confirms the execution of computational algorithm.
