“…They presented numerical results for the velocity, temperature, and volume fraction, the local Nusselt and Sherwood numbers. Kameswaran et al [29] presented a mathematical model for the two-dimensional steady incompressible convective heat and mass transfer from an isothermal wedge immersed in a nanofluid. They considered two types of water-based nanofluids and included the effects of the volume fraction parameter.…”

The MHD flow and heat transfer from water functionalized CNTs over a static/moving wedge are studied numerically. Thermal conductivity and viscosity of both single and multiple wall carbon nanotubes (CNTs) within a base fluid (water) of similar volume are investigated to determine the impact of these properties on thermofluid performance. The governing partial differential equations are converted into nonlinear, ordinary, and coupled differential equations and are solved using an implicit finite difference method with quasi-linearization techniques. The effects of volume fraction of CNTs and magnetic and wedge parameters are investigated and presented graphically. The numerical results are compared with the published data and are found to be in good agreement. It is shown that the magnetic field reduces boundary layer thickness and increases skin friction and Nusselt numbers. Due to higher density and thermal conductivity, SWCNTs offer higher skin friction and Nusselt numbers.

“…Moreover, they tracked down that the upsides of nondimensional paces of mass exchange, paces of warmth move, and paces of speed improve with strengthening upsides of the attractive boundary. The recognition of Soret impacts on limit layer stream of nanofluid over the wedge which is isothermal and it will be been examined by Kameswaran et al 19 Some basic aspects were analyzed by many renowned researchers in the enhancement of thermal transfer using nanofluid over wedge geometry 20–22 …”

This paper aims to examine the effects of singleand multi-walled carbon nanotubes (CNTs) nanoparticles on heat transfer enhancement and inherent irreversibility in the boundary layer of water base nanoliquid flow over a convectively heated moving wedge with thermal radiation. Manipulation of the angle positioning towards the flow stream provides the opportunity for comparing physical aspects in the flow states, where three main geometries of the well-known Falkner-Skan problem include: (i) the flat plat (named Blasius flow), (ii) the wedge, and (iii) the vertical plate (named Hiemenz stagnation flow) have been considered to present a comprehensive development of this significant problem. Applying suitable similarity constraints, the model partial differential equations are transformed into a set of nonlinear ordinary differential equations. Solutions are obtained analytically via optimal homotopy asymptotic method and numerically via shooting technique coupled with the Runge-Kutta-Fehlberg fourth-fifth scheme. The impacts of solid volume fraction of carbon nanoparticles along with other germane factors, such as wedge angle, velocity ratio parameter, Biot number, thermal radiation, and so forth on velocity and thermal

“…Furthermore, they found that the values of nondimensional rates of mass transfer, rates of heat transfer and rates of velocity enhance with intensifying values of the magnetic parameter. The observance of Soret effects on boundary layer flow of nanofluid over an isothermal wedge has been discussed by Kameswaran et al 27 Siva Raman et al 28 cognized numerical solutions for the Hiemenz flow, heat transfer characteristics of a nanoliquid over a wedge occupied with porous media in the presence of injection/suction due to solar energy. Salem et al 29 probed the boundary layer flow and heat transfer flow of a Cu‐water–based nanofluid over the surface of a permeable wedge by using the Tiwari and Das model and concluded that the velocity ratio parameter intensified with stepped‐up values of magnetic field parameter and suction parameter.…”

A comparison between the unsteady and steady magnetohydrodynamics Tiwari-Das model Williamson nanofluid flow through a wedge occupied by carbon nanotubes of multiwalled type nanoparticles and kerosene as base fluid is presented in this analysis. A suitable similarity variable technique is adopted to transmute the governing partial differential equations into a set of nonlinear ordinary differential equations (ODEs). To solve these ODEs together along with boundary conditions, we have utilized finite element analysis. The behavior of concentration, temperature, and velocity sketches for diverse values of the pertinent parameters is plotted through graphs. The impact on the above parameters on the rates of velocity, heat, and concentration is also evaluated and depicted through tables. It is noted that as the values of nanoparticle volume fraction parameter rises, the rates of temperature increase in both the unsteady and steady cases.
