Effects of injection (suction) on a steady mixed convection boundary layer flow over a vertical cone

Abstract

PurposeThe purpose of this paper is to study the steady mixed convection flow over a vertical cone in the presence of surface mass transfer when the axis of the cone is inline with the flow.Design/methodology/approachIn this case, the numerical difficulties to obtain the non‐similar solution are overcome by applying an implicit finite difference scheme in combination with the quasilinearization technique.FindingsNumerical results are reported here to display the effects of Prandtl number, buoyancy and mass transfer (injection and suction) parameters at different stream‐wise locations on velocity and temperature profiles, and on skin friction and heat transfer coefficients.Research limitations/implicationsThermo‐physical properties of the fluid in the flow model are assumed to be constant except the density variations causing a body force term in the momentum equation. The Boussinesq approximation is invoked for the fluid properties to relate the density changes to temperature changes and to couple in this way the temperature field to the flow field.Practical implicationsConvective heat transfer over a stationary cone is important for the thermal design of various types of industrial equipments such as heat exchangers, conisters for nuclear waste disposal, nuclear reactor cooling systems and geothermal reservoirs, etc.Originality/valueThe combined effects of thermal diffusion and surface mass transfer on a vertical cone has been studied.

Anisotropic slip magneto-bioconvection flow from a rotating cone to a nanofluid with Stefan blowing effects

“…Heat transfer from a rotating vertical cone arises in many thermal engineering and materials synthesis operations including nuclear reactor cooling systems and spin coating etc. [31]. The fluid near the surface of the body is forced outward in the radial direction when an axisymmetric body rotates in a forced flow field.…”

“…Anilkumar and Roy [37] numerically simulated the unsteady mixed convection flow on a rotating cone. Ravindran et al [31] analyzed mixed convection boundary layer flow with uniform suction or injection from a cone. Compressibility effects on laminar free convection flow over a vertical cone were examined computationally by Pop [36] and Bapuji et al [38].…”

“…Nadeem and Saleem [ 8 ] analyzed the nanofluid through a rotating cone. The convective fluid flow with suction/injection over a rotating cone was presented by Ravindran et al [ 9 ]. Chamkha and Al Mudhaf [ 10 ] investigated the mass and heat transmission in MHD fluid flow.…”

Unsteady MHD bio-nanoconvective anistropic slip flow past a vertical rotating cone

“…Similar solutions for cone geometries exist when temperature is considered to vary as a power function of distance along a cone ray [3]. Many studies have been communicated deploying numerical and analytical methods to study various aspects of rotating cone problem [3][4][5][6]. Raju [7] has considered the influences of the thermophoresis and thermal radiation on mixed convection heat and mass transfer phenomena past a vertical rotating cone in a fluid saturated porous medium.…”
