Ethanol and biodiesel, which both belong to the first generation of biofuel technology, are the two most popular forms of biofuels now in use. In order to create next-generation biofuels using waste, cellulosic biomass, and algae-based resources, the Bioenergy Technologies Office (BETO) is working with business. The present article is designed to study the effect of tetra hybrid nanoparticles with the utilization of the novel Hamilton and Crosser model and catalytic reaction on binary fluid with the consideration of ethanol biofuel as a base fluid. Ethanol comprising tetra hybrid nanoparticles and heterogeneous catalytic reaction amplifies thermal conductivity and significantly increases brake thermal efficiency and reduces brake-specific fuel consumption in diesel engines. Therefore, the aim of this article is a theoretical checkup that is related to heat and mass transport of biofuel flow considering binary fluid accompanied with autocatalysis reaction and novel tetra hybrid nanoparticles on biofluid flow subjected to a Riga wedge. Transportation of heat via nonuniform heat source/sink, thermal radiation, and thermal conductivity are in our consideration. The mathematics of the assumed problem generates the system of non-linear partial differential equations from basic equations of momentum, energy, and mass. The usage of non-dimensional variables gave a system of non-linear ODEs with boundary conditions which are further dealt with in the Lobatto111A scheme. The results are obtained for stretching/shrinking wedge with several parameters. From obtained results, it is observed that the velocity field diminishes owing to magnification in Weissenberg number and Casson fluid parameter. The temperature field diminishes by amplifying heat generation, thermal radiation, and variable thermal conductivity parameter. Concentration distribution escalates by rising homogeneous reaction parameters.

Exploration related to chemical processes in nanomaterial flows contains astonishing features. Nanoparticles have unique physical and chemical properties, so they are continuously used in almost every field of nanotechnology and nanoscience. The motive behind this article is to investigate the Cross nanofluid model along with its chemical processes via auto catalysts, inclined magnetic field phenomena, heat generation, Brownian movement, and thermophoresis phenomena over a symmetric shrinking (stretching) wedge. The transport of heat via nonuniform heat sources/sinks, the impact of thermophoretic diffusion, and Brownian motion are considered. The Buongiorno nanofluid model is used to investigate the impact of nanofluids on fluid flow. Modeled PDEs are transformed into ODEs by utilizing similarity variables and handling dimensionless ODEs numerically with the adoption of MATLAB’s developed bvp4c technique. This software performs a finite difference method that uses the collocation method with a three-stage LobattoIIIA strategy. Obtained outcomes are strictly for the case of a symmetric wedge. The velocity field lessens due to amplification in the magneto field variable. Fluid temperature is amplified through the enhancement of Brownian diffusion and the concentration field improves under magnification in a homogeneous reaction effect.

Prandtl Eyring fluid and stretchable wedge have multiple usages in many industries. The present study aims to investigate the impact of modified Buongiorno trihybrid nanofluid on Prandtl Eyring fluid past a wedge with the addition of various influences like endothermic/exothermic reactions, thermal radiation, and thermal conductivity, Cattaneo-Christov double diffusion. Aluminium alloys (AA7072), Aluminium alloys (AA7075) and Silver (Ag) are used as nanocomponents. Prandtl Eyring fluid is employed as a conventional liquid in the preparation of nanofluids by blending nano components into the base fluid. Further, the flow model is imposed with Modified Buongiorno nanofluid. By using the similarity approach, the proposed mathematical flow model of partial differential equations (PDEs) is turned into highly nonlinear ordinary differential equations (ODEs). Throughout the whole range of material parameters, the solution for the ensuing nonlinear boundary value issue is given by employing the finite element method (FEM). The numerical results of Prandtl Eyring ternary HNF motion, thermal and solute profiles are performed through graphical amassment on the collected data and discussed in detail. The numerical significances of material sections, such as the frictional force, local Nusselt quantity, and local Sherwood number requirements, are supplied in tabular form. Further, it also presents the validation and performance characteristics of the proposed device with previously published work and found excellent accuracy. In comparison to hybrid nanoparticles, the consequences reveal that heat transmission is amplified in the case of tri-hybrid nanoparticles. The numerical consequences show that the heat transfer amount reduces in the situation of exothermic reactions parameter Ω < 1 and rises due to magnification in the status of endothermic reactions parameter Ω > 1.

Solar energy is the most important source of thermal energy that comes from the sun. This kind of energy has enormous potential applications in fields of technology such as photovoltaic panels, renewable power, solar light poles, and solar pumps used for water extraction. The era in which we are living is all about the applications of solar energy in industrial sectors most importantly in solar sports car manufacturing. This article presents a new way of thinking about the heat transport analyses of photovoltaic hybrid vehicles, by factoring Casson-Sutterby liquid with the inclusion of various effects like variable thermal conduction, thermal radiation, heat generation, and tetrahybrid nanoparticles. To solve the modelled equations in regards to both momentum and energy, another well-computational approach known as the Cash and Carp method was used. The effects of a wide variety of factors on temperature, shear stress, and velocity fields, as well as the surface drag coefficient and Nusselt number, are briefly described and illustrated in the form of tables and figures. It then found that the thermal radiation, heat production, and thermal conductivity parameters and insertion of agglomerative tetrhybrid nanoparticles in the base fluid amplify heat transfer rate, it has been shown that the performance of the solar car increases in terms of heat transition. In comparison to standard nanofluid, tetrahybrid nanofluid is the most effective medium for the transmission of heat. From the regression analysis, it is observed that the error in terms of Nusselt number is smaller 0.0151 for the case ε = 1.5, and increases to 0.0151 in the case of ε = 2.5. Relative percentage error is smaller 4.62% in the case of heat generation Q= 0.7 but a maximum of 15.8% in the case of thermal radiation Rd = 2.

The improvement of heat transfer is the focus of this paper’s innovative theoretical ternary hybridity nanofluid (HNF) prototype. In this examination, blood is employed as the conventional liquid, and the tri-hybrid nanomolecules Au, Ag, and TiO2 are submerged in it. The extension has been made in the conventional Tiwari and Das hybrid nanofluid model to transform it for the case of a trihybrid nanofluid. By consuming resemblance variables and the Keller box methodology (KBM) to resolve the ordinary differential equations (ODEs) resulting from the conversion of the liquid flowing and temperature formulas. The results are graphed, and it is shown that the trihybridity nanofluid (THNF) has greater thermal conductance than the HNF. The heat transference rate increases in the situation of an augmentation in thermal conduction and radiation effect which helps remove the toxic plaque from the blood flowing through arteries. This additional heat produced because of amplification in thermal radiative fluxing is used to open rigid arteries through which the blood is flow.
