Profile control schematic diagram

Methodology appropriate for the measuring of DTA profiles has been extensively reviewed [12,13]. A schematic diagram illustrating the essential aspects of the DTA technique is shown in Fig. 3. Both the sample and reference materials are contained within the same furnace, whose temperature program is externally controlled. The outputs of the sensing thermocouples are amplified, electronically subtracted, and finally shown on a suitable display device.

The LD-17 is an electrochemical voltametric detector operating under diffusion-controlled conditions.) The effluent H2S concentration never exceeded 250 ppm and was usually less than 50 ppm. Evolution profiles were recorded by a strip-chart recorder. Figure 1 shows the schematic diagram of the H2S evolution system. 

Figure 9.22 A schematic diagram showing the concentration profile of permeant in a liquid membrane when the Process is (A) diffusion-controlled, (B) boundary-layer-controlled, and (C) reaction-rate controlled. The concentration profile in the membrane in absence of boundary-layer and reaction-rate effects is shown for comparison.17...

Figure 3 is a schematic diagram of the equipment that is used for precipitation, filtration and washing, all at a high pressure. It consists of a CO2 delivery system and an autoclave with a volume of 400 ml. The vessel is equipped with baffles, a stirrer and a water-jacket for heating and cooling. The bottom of the autoclave contains a filter plate with a pore-size of 10 micrometers. The carbon dioxide flow to the precipitator is controlled by an air operated needle valve in combination with a pressure transducer and a programmable controller to impose a predetermined pressure profile. 

Wall jets are bounded by a solid surface, the wall, on one side while the outer region of the flow is in contact with the ambient fluid. Wall jets find many applications such as cooling of surfaces, boundary layer control, building ventilation, energy dissipation etc. Jets emanating from sluices and other hydraulic structures close to the bed of channels need special attention to provide the necessary protective works. Prediction of the velocity profiles in the case of a wall jet is more difficult compared to the free jet. After a short distance downstream of the outlet, all jets tend to behave in a similar fashion. The schematic diagrams of a plane wall-jet and the boundary conditions used in the simulation are shown in Figure 1.
