The magnitude of thermocapillary convection in larger melt volumes
Advances in Space Research, 1981Abstract Thermocapillary convection (TC) has been studied experimentally in a NaNO 3 -melt of some cm 3 volume. TC has been identified, its streamlines and flow velocities have been visualized and measured. TC dominated over natural convection in this ground based experiment and will be a very significant flow phenomenon in the relevant μ-g ...

Finite volume simulation for convective heat transfer in wavy channels
Heat and Mass Transfer, 2015The convective heat transfer characteristics for a periodic wavy channel have been investigated experimentally and numerically. Finite volume method was used in numerical study. Experiment results are used for validation the numerical results. Studies were conducted for air flow conditions where contact angle is 30°, and uniform heat flux 616 W/m2 is ...

Finite volume methods with local refinement for convection-diffusion problems
Computing, 1994This paper deals with the construction of conservative cell-centered approximations on locally refined grids for convection-diffusion second- order elliptic equations that have optimal order of convergence and satisfy the discrete maximum principle. In order to produce monotone schemes for convection-diffusion problems a variety of upwinding strategies

A theory of convective gas motion in a cylindrical volume
Technical Physics Letters, 2005The convective motion of gas in the gravitational field is described for an axisymmetric body with the cylinder ends maintained at different temperatures. A system including the equation of heat conduction, the Navier-Stokes equations, and the continuity equation is analyzed. The convective velocity components vz′ (r, z), vr′ (r, z) and the temperature
