Ultrapure water - Wikipedia

Ultrapure water (UPW), high-purity water or highly purified water (HPW) is water that has been purified to uncommonly stringent specifications. Ultrapure water is a term commonly used in the semiconductor industry to emphasize the fact that the water is treated to the highest levels of purity for all contaminant types, including: organic and inorganic compounds; dissolved and particulate

Convection (heat transfer) - Wikipedia

Convection (or convective heat transfer) is the transfer of heat from one place to another due to the movement of fluid. Although often discussed as a distinct method of heat transfer, convective heat transfer involves the combined processes of conduction (heat diffusion) and advection (heat transfer by bulk fluid flow).Convection is usually the dominant form of heat transfer in liquids and gases.

District Cooling System - an overview | ScienceDirect Topics

The supply temperature is normally 6 or 7°C, but an ice mixture of 0°C is sometimes used. Customers heat the chilled water in the supply pipe by cooling air supplied to a building or a industrial process. The typical temperature in the return pipe is 1217°C. The water is again chilled when it circulates through the cold-generation plant.

Wall-to-Bed Heat Transfer in Bubbling Fluidized Bed

Apr 27, 2021 · Measurements were carried out to investigate the wall-to-bed heat transfer in a cross-flow bubbling fluidized bed under continuous solids exchange. The experiments were performed with different tube bundle heat exchangers immersed in a lab-scale gassolid fluidized bed cold flow model 0.4 m × 0.2 m in cross section. Geldart group B particles were used, and the gas velocity, the solids
