The telecommunication industry is concerned about the energy costs of its operating infrastructure, and the associated greenhouse gas emissions. At present, more than half of the total energy consumption of data centers is for the power and cooling infrastructure that supports the storage and communication equipment. One method of reducing energy consumption is an approach called ―free air cool...

Abstract An experimental study was conducted to quantify the flow characteristics of the wall jets pertinent to trailing edge cooling of turbine blades. A high-resolution stereoscopic particle image velocimetry (PIV) system was used to conduct detailed flow field measurements to quantitatively visua...

Several generalized state-space models arising from a semi-discretization of a controlled heat transfer process for optimal cooling of steel profiles are presented. The model orders differ due to different levels of refinement applied to the computational mesh. 1 The model equations We consider the problem of optimal cooling of steel profiles. This problem arises in a rolling mill when differen...

The thermodynamics of laser cooling of solids is analyzed. Using the general theory of radiation entropy, the important roles of the optical frequency and the photon distribution function in determining the radiation entropy are identified. The usefulness of a narrow-band approximation is established for a wide range of radiant sources. This approximation is then applied to compare the entropie...

Compression molding process can potentially be used to make high precision glass lenses. In a lens molding process, glass raw material is heated above its transition temperature and is subsequently pressed between the two mold halves into a lens shape. Controlled cooling (annealing) of the formed lens is then carried out with the molds in a closed position in order to enable uniform cooling of ...

the present paper describes the designing of a thermally and economically optimum mechanical draft counter-flow wet cooling tower. the design model allows the use of a variety of packing materials in the cooling tower toward optimizing heat transfer. once the optimum packing type is chosen, a compact cooling tower with low fan power consumption is modelled within the known design variables. mor...

Abstract: The horizontal continuous casting process has received a significant attention for near net shape casting of non ferrous metals and alloys. Numerical Simulation has been widely used for process design and optimization of continuous casting process. In the present study, a 3-dimensional heat flow model was developed to simulate the heat transfer and solidification in a horizontal b...

The southeastern tropical Indian Ocean (SETIO) was characterized by unusually cold sea surface temperature (SST) and strong northwestward alongshore surface winds during 1994. Using multi-source data sets including ocean model simulation, two key processes are identified for the SETIO cooling. Entrainment cooling produced most of the negative SST anomaly near the coast whereas evaporative cooli...
