Waves on the surface of a vapor film under conditions of intensive heat fluxes
Physical Review E, 2008We investigate surface waves on the interface between a thin vapor film and a layer of liquid in the presence of a high steady heat flux. This problem arises when a metal surface heated to a high temperature is immersed into a cold liquid. The general boundary conditions, which take into account the temperature dependence of saturation pressure on the ...

Temperature Rise and Heat Flux Induced by Laser Beam with Double-Gaussian Intensity Distribution
Japanese Journal of Applied Physics, 1995The temperature rise and heat flux induced by a CW (continuous wave) double-Gaussian-distributed laser beam have been investigated numerically in a semi-infinite substrate. The temperature-dependent thermal conductivity and surface reflectivity of the substrate material are incorporated in the calculation model.

Thermal Optimization of Circular Bodies Submitted to an Intense Heat Flux by Constructal Design
2009 3rd Southern Conference on Computational Modeling, 2009The present work studies the optimization of a circular body with an intense heat flux by Constructal Design. The problem concerns the minimization of the global thermal resistance of a three-dimensional structure submitted to an intense uniform heat flux, which is cooled through microchannels inserted in the circular body.

The heat transfer enhancement can be achieved through the secondary flow. It is found that absolute vorticity flux along the main flow can describe the secondary flow intensity and correspond to the heat transfer enhancement averaged in span wise direction. Investigations to verify this phenomenon are reported. The results show that there has a similar

Abstract For ITER, the potential material damage of plasma facing tungsten-, CFC-, or beryllium components during transient processes such as ELMs or mitigated disruptions are simulated numerically using the MHD code FOREV-2D and the melt motion code MEMOS-1.5D for a heat deposition in the range of 0.5–3 MJ/m2 on the time scale of 0.1–1 ms.
