Thermal performance can be enhanced due to the mixing of nanoparticles in base fluid. This research discusses the involvement of ternary hybrid nanoparticles in the mixture of pseudo-plastic fluid model past over a two dimensional porous stretching sheet. Modelling of energy equation is carried out in the presence of external heat source or sink and viscous dissipation. The flow presenting equations and derived in Cartesian coordinate system under usual boundary layer theory in the form of complex coupled partial differential equations (PDEs). The derived PDEs have been converted into corresponding ordinary differential equations (ODEs) with the engagement of suitable transformation. The engineers, scientists and mathematicians have great interest in the solution of differential equations because to understand the real physics of the problem. Here, finite element scheme has been used to approximate the solution of the converted problem. The contribution of several emerging parameters on solution have been displayed through graphs and discussed. It is recommended that the finite element method can be engaged to approximate the solution of nonlinear problems arising in modelling the problem in mathematical physics. [ABSTRACT FROM AUTHOR]

The nanofluid technology has added significant contributions towards heat exchange increase and decrease in energy loss. This article focuses, to analyze the heat and mass transfer for two distinct hybrid nanofluids, namely (Ag-CuO/NE), (Ag-CuO/SE), under the impact of magnetic field and Rosseland radiation over a rotating cone embedded in the porous medium. The set of non-linear partial differential equations is derived with help of boundary layer approximation. A suitable and appropriate similarity set is used to obtain a dimensionless set of equations which, are then converted into ordinary differential equations. The problem is tackled numerically with the BVP-4c technique, keeping tolerance at 10−06. The influence of flow study parameters is discussed with help of graphical and tabulated data. The study shows that (Ag-CuO/NE) hybrid nanofluid has produced better heat and mass transfer rates as compared (Ag-CuO/SE) hybrid nanofluid. Therefore, the study suggests more frequent use of (Ag-CuO/NE). [ABSTRACT FROM AUTHOR]

[Display omitted] • Jet flow of ternary nanofluid is considered. • Modified Buongiorno's model is used for the bioconvective flow of gyrotactic microorganisms. • Chemical Reaction is included. • Three different types of nanoparticles rGO , F e 3 O 4 , T i O 2 are suspended into H 2 O. • Thermophoresis and Brownian motion are discussed along with the nanoparticle volume fraction. A few typographical errors have been identified in our paper titled "Implementation of modified Buongiorno's model for the investigation of chemically reacting rGO - F e 3 O 4 - T i O 2 - H 2 O ternary nanofluid jet flow in the presence of bio-active mixers". This corrigendum addresses those errors however, these errors have no impact on the obtained results. [ABSTRACT FROM AUTHOR]

[Display omitted] The analysis of enhancing the heat transfer of a traditional fluid by adding nanoparticles was effectively studied by many researchers across the globe. In later stages, these nanofluids were made chemically stable by suspending an additional inert nanoparticle thus forming a hybrid nanofluid. The heat transfer characteristics of hybrid nanofluids are discussed in various aspects. Considering these studies, the heat and mass transfer characteristics of ternary nanofluid formed by suspending three different nanoparticles is analysed in this article. The self-propelled microorganisms move within the nanofluid due to the density gradient and it ensures proper mixing of nanoparticles. In order to achieve proper bioconvection caused by microorganisms, the nanoparticle concentration is assumed to be dilute and the fluid with these characteristics is assumed to flow as a jet past a stretching sheet. The mathematical model to analyse such a characteristic flow is framed using the modified Buongiorno's model that describes the impact of volume fraction, thermophoresis and Brownian motion. The mathematical model obtained will be further converted into non-linear differential equations that are solved through the RKF - 45 method. The results obtained through this method are interpreted graphically and the impact of fluid flow parameters on the heat and mass transfer rates are tabulated. It is perceived that the mixed convection parameter enhances the velocity profile. Similarly, the increase in the Brownian motion and thermophoresis enhances the thermal profile. Meanwhile, the increase in the nanoparticle volume fraction helps in enhancing the thermal conductivity and thus the temperature is found to be increasing. [ABSTRACT FROM AUTHOR]
