TL;DR: In this article, the fluid flow and heat transfer features of cellular metal lattice structures made from copper by transient liquid phase (TLP) bonding and brazing of plane weave copper meshes (screens) were experimentally characterized under steady-state forced air convection.

TL;DR: In this article, the authors analyzed the magnetohydrodynamic (MHD) nanofluid flow and heat transfer between two horizontal plates in a rotating system and determined the velocity and temperature profiles as well as the skin friction coefficient and the Nusselt number numerically.

TL;DR: In this article, a method for calculating the distribution of temperature and stress within a single metallic layer formed on the powder bed in rapid prototyping with the selective laser melting method is proposed.
Abstract: A method for calculating the distribution of temperature and stress within a single metallic layer formed on the powder bed in rapid prototyping with the selective laser melting method is proposed. The solidified layer is assumed to be subjected to plane-stress deformation and the two-dimensional finite element methods for heat conduction and elastic deformation are combined. In the simulation, the finite element mesh is constructed on the surface of the powder bed. The heat caused by laser irradiation is given to the elements under the laser beam. Shrinkage due to solidification is assumed to result in only the change of the layer thickness. In the elastic finite element simulation, the Young's modulus of the solidified part is expressed as a function of temperature. To simplify the calculation, the whole area is treated to be continuous, and the powder bed and the molten part are assumed to have a very small Young's modulus. The heat conduction and the elastic finite element calculations are carried out alternately. The obtained results of deformation and tensile stress distribution show the possibility and places of cracking of the layer during forming.

TL;DR: In this article, it was shown that large heat generation along the deep-earthquake fault zone and effective heat transfer in the upper mantle above the deep earthquake zone is required to explain the heat flow pattern across island arcs and marginal seas.

28 Sep 1992TL;DR: In this paper, a surface heating blanket assembly for soil remediation is described, which consists of a metallic furnace belt with tubular electric heating elements inserted between the rungs thereof and making low resistance contact therewith.
Abstract: This invention comprises a surface heating blanket assembly useful for soil remediation. The assembly principally comprises a metallic furnace belt with tubular electric heating elements inserted between the rungs thereof and making low resistance contact therewith. The furnace belt heater is capable of being rolled and dragged, and flexibly conforms to the earth's surface for maximum heat transfer to the soil. A layer of permeable insulation and an impermeable sheet may be placed on top of the heater. A vacuum may be pulled under the impermeable layer by means of a hole therethrough connected to a vacuum pump.
