Flow liquid flows

In annular flow, liquid flows as a thin film along the pipe wall and gas flows in the core. Some liquid is entrained as droplets in the gas core. At veiy high gas velocities, nearly all the liquid is entrained as small droplets. Inis pattern is called spray, dispersed, or mist flow. 

Reverse flow Liquid flowing from the inlet on one side of the tray (around a center baffle) reverses its direction at the other side of the tray, and flows back to the downcomer on the same side of the tray where the inlet is. 

Split flow Liquid flow across the tray is split into two or more flow paths.

Govier et al. (G5, G6, B14) have correlated flow patterns in terms of the location of the two minima and the maximum observed in the pressure drop vs. gas-liquid volumetric feed ratio (12 ) curves (cf. Fig. 2). Gas-liquid ratios, gas flow, liquid flow, pipe diameter and gas-phase density were investigated for the air-water system in isothermal flow. From the correlations presented (as against a function, when n varies...

In the condenser and evaporator there is a vapour flow, liquid flow, interface position, radial heat transfer with kinetic reaction pressure, liquid pressure, vapour pressure, condensation and evaporation, shear stress, geometry, adhesion pressure, convective heat transport, radial heat transfer under the influence of the gravity field. 

Cross flow Liquid flowing across a plate (rather than straight down through die holes) so that it fells to the plate below through a channel at one side of die plate. 

Radial flow Liquid flowing radially from, or to, an inlet (or outlet) located at the center of the tray, to (or from) downcomers (or inlets) at the tray periphery. 

Capillary Flow Liquid flow in response to a difference in pressures across curved interfaces. See also Capillary Pressure. 

Dispersed flow. Liquid flows as individual droplets in a high-velocity turbulent gas stream. 

Annular-flow. Liquid flows as a thin film around the inner surface of the column. The film thickness is not usually a function of position within the column, but the gas-liquid interface is not smooth. 

A thermomechanical valve is a device that regulates fluid flow (either gas flow, liquid flow, or slurry flow) by using an actuator which deforms under different temperatures to open, close, or partially obstruct various channels. 

Perhaps the most important property that differentiates solids and liquids is flow. Liquids flow and take the shape of the container, whereas solids do not flow and tend to retain their shape. The optical properties of liquids and some solids can also be quite different. For example, some solids change the polarisation of light whereas liquids do not. With these ideas in mind, it is not surprising that early investigators who found substances which did not neatly fall into these categories noted their findings and began to ask questions. 

The fourth type of liquid distribution device is a bubble cap tray, originally designed for application in fractionation towers. This device employs a number of bubble caps laid out on a regular pitched pattern on a horizontal tray. The bubble cap distributor works on a vapor-assist principle that offers a relatively stable operation compared to a chimney device. The bubble cap is a cap centered concentrically over a standpipe. The sides of the cap are slotted for vapor flow. Liquid flows under the cap and is aspirated by the vapor, flowing upward in the aimular area between the cap and the standpipe, and then down through the standpipe. 

The third class of scrubber is called cross-flow. This device contacts a horizontally flowing gas stream with a vertically descending liquid flow. Thus, cross-sectional area for gas flow is different from the area for liquid flow. Liquid flow rates can be 40% lower per 1,000 CFM of air than when the gas flow area is the same as the liquid flow area. Even at these reduced liquid rates satisfactory wetting of the tower packing is obtained.

This stage involves two processes migration of moisture within the material to the surface and removal of the moisture from the surface. The former can occur by three mechanisms vapour flow, liquid flow and diffusion. The latter is usually only significant when the moisture content drops below the saturation point. Liquid flow dominates with convective drying, where...
