Influence of shape factor on hybrid nanomaterial in a cross flow direction with viscous dissipation

The study of shape effects in nanofluids plays a vital role in the fluid flow as well as heat propagation. Hence, the different shape factors of molybdenum disulfide MoS2 on a stretchable disc with rotation under the effect of the magnetic field, chemical response, and activation energy are examined. The set of partial differential equations is converted into ordinary differential equations (ODEs) by using von Karman's transformations, and the obtained ODEs are solved by using Runge‐Kutta‐Fehlberg 45 and shooting techniques. The numerical computations are made by utilizing well‐known maple 17 software. The different physical parameter effects on velocity, temperature, and concentration curves, as well as skin friction and Sherwood numbers, are analyzed through graphs. It is noted that the larger values of solid volume fraction enhances the drag coefficient and reduces the rate of heat transfer. It is further observed that the curve of a viscous fluid is always lesser than curve of a nanofluid.

Flow and heat distribution over a convergent or divergent channel plays a major role in aeronautical, pharmaceutical, dynamic, civil, climatic, and biomechanical engineering, as well as heat transfer through a porous medium, has piqued the interest of researchers due to its numerous aerospace and automotive manufacturing, including waste disposal, raw petroleum products, grain collection, porous coating, petroleum lagoons, groundwater pollution, packed-bed power plants etc. Further, addition of nanoparticles to base liquid will improve the thermal distribution. Based on the above affordable application the present study will focus on heat transfer enhancement in ternary nanofluids flows induced by stretched convergent or divergent channels. The mobility of ternary nanoparticles occurs in the porous zone. The uniform energy absorption and generation influence is included in the energy expression. Through the use of comparable variables, the flow expressions are transformed into a system of non-linear ODEs (ordinary differential equations). To tackle the problem, the Runge-Kutta-Fehlberg fourth and fifth order (RKF-45) scheme with shooting procedure is adopted. The nature of imposing limitations on physically significant quantities is explored and carried out. The augmentation in solid volume-fraction of both stretched/shrinked channels resulted a reduction in temperature. Furthermore, it is found that the increasing heat sink or source factor and Eckert number augmented the rate of energy transport in the diverging channel, but reverse nature is found in the converging channel. It is also noticed that the ternary nanofluid has a greater impact than the hybrid and mano-nanofluid.

The flow through a stretchable cylinder has auspicious uses in many industrial processes like thermal processing of food particles, liquid coating on photographic films and tubular heat exchangers. Motivated from these applications, heat transport through a stagnation-point hybrid nanoliquid flow past a permeable cylinder is scrutinized. Aluminum alloy and magnetite graphene oxide with water-based nanoparticles are considered. A uniform heat source/sink term is added in the energy equations. The noted novelty of this work is the application of the hybrid nanofluid along with the heat generation/absorption effect for stretchable cylinders which has not been considered in the open literature. The strong form of ordinary differential coupled equations is solved by the Runge–Kutta-Fehlberg-45 (RKF-45) numerical approach via the shooting technique. Graphical profiles are obtained and discussed at diverse physical parameters. Moreover, the drag friction and the Nusselt number are computed. The results have shown that the higher variation in causes a reduction in the velocity and an enhancement in the temperature curves. Further, it is noted that the velocity curves of magnetite graphene oxide is higher than aluminum alloy nanoparticles. The Nusselt number is larger for the aluminum alloy nanoparticles case as compared to the values achieved for the case of magnetite graphene oxide nanoparticles.
