Hybrid nanofluids are formulated with various kinds of base fluids. They are designed to provide good heat transfer performance. They can achieve this by dispersing various kinds of nanoparticles in the base materials. This new technology of formulating hybrid nanofluids has a wide range of applications in various industries such as solar energy, medical equipment, and aerospace. Keeping these applications in view, this study provides an insight into the effects of convective heat transport on a Hybrid nanofluid, across a rotating sheet with a variable heat source. In this investigation, the governing boundary layer partial differential equations were modified into the ordinary differential equations, by using the proper similarity transformations. Later, they were solved numerically, with the support of the Lobatto IIIA technique in MATLAB. The influence of the Richardson number on flow parameters was studied, and it was discovered that increasing Ri increases the velocity while decreasing temperature and concentration profiles. The impact of various other flow parameters on the flow fields and also on the behavior of Nusselt number, coefficient skin friction, and Sherwood number were studied and represented graphically. The outcomes were found to be in excellent accord when compared with quoted studies.
The current research looks at how the radiation affects the convective hybrid Casson 3D flow in the presence of suction. The fluid analysed was a hybrid nanofluid made up of Alumina (Al 2 O 3 ) and Copper (Cu) nanoparticles diffused in base fluid (Water). After simplification, the flow control equations were programmed and solved employing the MATLAB software and the bvp4c code. Figures depict the study's most important findings, such as the impact of several physical elements such as convection, radiation, and suction on the velocity profile, mass transfer, temperature field, friction factor, and heat transfer coefficient. According to the key findings, the Casson Hybrid nanofluid has a better property than normal fluids. It can also be deduced that as the scale of the radiation constraint strengthens, the temperature field improves. Tables were used to validate our findings with cited papers.
Viscous dissipation acts as an energy source and alters the temperature distribution, and extremely shear flows impact the fluid flow structure. Thus, the current study analyses the three-dimensional rotating Casson fluid flow across a linear extending sheet in the existence of internal energy and porous medium. The controlling equations for velocity, concentration, and energy of the steady flow are provided and simplified using the similarity transformations. The three-staged collocation technique, namely Lobatto III A was implemented in conjunction with MATLAB to solve the resulting equations. The physical characteristics of the relevant quantities were explained with the support of graphs. It was noticed that the velocity component decreased with the rise in the porosity parameter. For the improved values of the Eckert number, the temperature component increased. The influence of Eckert number, Casson parameter etc. on the Skin friction, the Nusselt number and the Sherwood number were assessed.
Natural convection occurs in fluid environments. Usually, it is facilitated by the buoyancy effect. It is significantly less efficient than forced convection, due to the lack of fluid motion. As a result, it is completely dependent on the buoyancy effect's strength and the fluid's viscosity. The current work investigates the convective flow of a three-dimensional Casson fluid across a rotating linear expanding sheet. The nonlinear governing equations of the steady flow were presented and reconstructed using appropriate similarity transformations. To solve the resultant equations, the three-stage collocation approach namely Lobatto IIIA was applied using MATLAB. Graphs were used to illustrate the physical properties of the required data. It was observed that while the primary velocity profile decreases as the Casson, convective, and rotational parameters increase, the secondary velocity profile exhibits the opposite behaviour. The effect of rotation, Casson parameter, and others on drag coefficient, heat transfer coefficient, and mass transfer coefficient was evaluated, interpreted, and found to be reasonably consistent with earlier research.
