...) or the total variation diminishing (TVD) flux limiters (FL), were introduced and implemented onto the unstructured grids. This implementation was carried out by constructing a local coordinate and introducing a virtual upstream node. Findings The procedure was validated by calculating the lid‐driven cavity...

... equation in the sub‐particles in the material. In the presented meshless method due to elimination of domain integration the computational efforts are decreased substantially. Findings Numerical results are presented for temperature distribution, heat flux and thermal conductivity. Numerical results...

... are initiated at time t¯ = 0 when the wedge is impulsively started from rest with a uniform velocity and a constant heat flux at the walls of the wedge is suddenly imposed. Design/methodology/approach The velocity of the main free stream is written in non‐dimensional form for t > 0...

... a bispherical coordinates system. The inner sphere is heated by a heat flux of constant density and the outer one is maintained isothermal. Design/methodology/approach The transfer equations are written by using a bispherical coordinates system. The Navier‐Stokes equations are solved and coupled...

...O.D. Makinde Purpose The hydromagnetic mixed convection flow of an incompressible viscous electrically conducting fluid and mass transfer over a vertical porous plate with constant heat flux embedded in a porous medium is investigated. Design/methodology/approach Using the Boussinesq...

... of the approximation of the flux term at the control volume (CV) faces. For highly orthotropic and anisotropic media, first order approximations produce inaccurate simulation results, which motivates the need for better estimates of the flux expression. In this article, a new approach to approximate the flux term...

... are influenced by freestream Mach number. The interaction between the shear layer on the spike and the conical‐reattachment shock wave causes the peak wall pressure and heat flux on the heat shield. The peak heat flux is shown to be a function of freestream Mach number and increases with increase in freestream...
