Hydraulics of air–water flow in a supercritical bottom ...

Each intake intercepts and transfers stormwater runoff to the main tunnel through a vertical drop shaft. The design of such an intake structure adjacent to densely populated residential areas (including some premium properties) is an engineering challenge. A bottom rack intake is proposed to intercept the supercritical flow.

Supercritical fluid - Wikipedia

Supercritical fluid extraction. The advantages of supercritical fluid extraction (compared with liquid extraction) are that it is relatively rapid because of the low viscosities and high diffusivities associated with supercritical fluids. The extraction can be selective to some extent by controlling the density of the medium, and the extracted ...

Air preheater - Wikipedia

Types. There are two types of air preheaters for use in steam generators in thermal power stations: One is a tubular type built into the boiler flue gas ducting, and the other is a regenerative air preheater. These may be arranged so the gas flows horizontally or vertically across the axis of rotation.
