A bed of granular medium (usually sand, but other materials can be used such as Ballotini or anthracite) is placed in a readily demountable tube through which water can be made to flow in either a downwards or upwards direction.
The test section tube and all tubing connections are transparent so that operation can be observed and the presence of air bubbles easily detected. All metal fittings are corrosion resistant.
Pressure drop across the bed can be measured either by a 0.5m length water differential manometer or a 0.5m length Mercury manometer (see recommended accessories), depending on the magnitude. Valves are fitted for isolation of various parts of the circuit, together with air release valves.
Flow from a laboratory tap passes through a constant head tank, which also allows air bubbles to be released, and is controlled by hand with a needle valve. The rate of flow is indicated by a variable area meter.
No power connections are required and the whole apparatus can be lifted and transported by one person. Test material (Ballotini) for the packed bed is supplied but Mercury for the manometer is not included.
The pressure rod moves boththe pistons in the brake master cylinder and the braking process is started. By pressing the lever the outer valve can be seen to open. The piston rod with diaphragm disk moves forward.

The plate has two different surfaces so as to study the effect of surface conditions on the boundary layer. Side bodies can be used in the measuring section. The experimental unit used in the aerodynamics trainer allows the boundary layer on a flat plate to be studied. Thus the boundary layer phenomena can experience interference with a degressive or progressive pressure curve and, for example equalise the friction loss of the flow. For this purpose, air flows along the plate, parallel to the surface.
Learning Objectives And Experiments:
Boundary layer interference with
Degressive/progressive pressure curve
Internal friction of gases
Influence of surface roughness on the formation of a boundary layer
Investigation of the boundary layer on the flat plate.
Absorption is used to remove one or more gaseous components from a gas flow using a solvent. The flow rates of the gas components are displayed. A compressor delivers the gas mixture into the lower section of the absorption column. First of all, a CO2 and air gas mixture is produced. Water is used as the solvent. The CO2 is absorbed by the downward flowing water. As the pressure is reduced and the temperature is increased, the solubility of the CO2 falls. A heater heats the water. A water jet pump generates the vacuum in the desorption column and causes the CO2 gas to be emitted from the water. To separate the absorbed CO2, the charged water is then fed from the lower section of the absorption column into a desorption column. It is possible to adjust the mixing ratio using valves. A pump then delivers the regenerated solvent back into the absorption column. The water temperature can be controlled. Flow rate, temperature and pressure are continuously measured. In the column, part of the CO2 is separated in the counterflow with the solvent.
