... technique is unique because it avoids determining the effective thermal diffusivity and quantifying the boundary heat flux. The technique is used to measure the effective thermal conductivity of glass-water, glass-air, and steel-air systems. These systems yield solid-fluid conductivity ratios of 1.08, 25.7...

...G. G. Nasr; R. A. Sharief; A. J. Yule A novel technique is described for investigating spray cooling of moving hot surfaces. An experimental investigation is described for vertically downwards water sprays impinging on a horizontal steel annulus of 250 mm diameter with a surface temperature up...

...Yoav Heichal; Sanjeev Chandra Thermal contact resistance between molten metal droplets (aluminum alloy 380 and bismuth) and solid plates (steel and brass) was measured experimentally. The diameter of the droplets was 4 mm , and droplet impact velocity ranged between 1 and 3 m ∕ s . Substrate...

... that is partially wet with evaporable water. The predicted water vapor pressures at the evaporation front are quite high and could conceivably cause the concrete to spall. The model is quantitatively compatible with spallation events observed during tests involving the pouring of molten steel onto concrete...

... problems are solved and the effects of roughness and packed bed structures are also examined. The numerical solution of the thermal conduction problem through the periodic regular arrangement of steel spheroids in air is determined using the Finite Element Method. The numerical results are compared...
