Waves reflect off the surfaces of the model and from sides of the tank. This can be a major limitation on towing tanks where the productively of the whole facility is determined by the settling time after a run has been completed. All tanks have resonant frequencies and often these lie within the working frequencies that are generated in the tank. A good beach will absorb much of the energy after is has passed the model but has little effect on cross-waves or models reflected from the model. Wave makers incorporate proven software techniques for wave generator control and can include software links to towing carriages to optimise test duration. Wave Technology is a rapidly advancing science new or modified products are continually being developed to meet unique experimental needs, including those associated with the offshore industrys deep-sea exploration research programmes. Active absorbing wavemakers dramatically increase the performance of a tank by prolonging the time that an experiment can run without the build up of spurious waves and also by decreasing the settling time between runs.

The apparatus has two transparent tanks, mounted one above the other. A variable-speed pump transfers water from the reservoir (in the base of the unit) into the upper tank. PLC Process gives students and engineers practical experience of the principles and application of programmable logic controllers (PLCs). The object is to connect and program an external, programmable logic controller to monitor and control the level and flow rate of water in a two-tank system. The pump control is on or off, but a manual control allows the user to set the speed. A float switch in the reservoir monitors the level of water. The water can drain down to the lower tank and then back into the reservoir. Solenoid valves may be individually opened or closed to control and redirect the movement of the water.

The primary separation operation for crude oil occurs when the crude stream flows through a vessel of sufficient capacity to allow gravity separation of the gas, liquid hydrocarbon and water phases. The three phase separator demonstration apparatus is a small scale vessel that performs continuous separation of a mixture of oil, air and water. The process has manual control valves with rotameters and is intended to demonstrate oilfield separation principles with basic visual manual operation. It is available in horizontal and vertical orientations. This trainer includes a clear horizontal primary separator vessel.
Function:
This fluid mixture then flows into a separator vessel fabricated of clear materials. This process trainer blends air, water and refined oil to emulate a crude oil stream. The oil and water are recycled; the air is vented to atmosphere.

The rolling thin film oven (RTFO) test is used to measure the effect of heat and air on a moving film of semisolid asphalt binder. The results of this treatment are determined from measurements of the binder properties before and after the test. The superpave PG binder specification looked for tests which would closely simulate field performance. Hotmix asphalt binder experiences significant aging during the manufacturing and laying process. Repeat ability of the test is directly related to the accuracy with which the oven temperature can be maintained and the re producibility of the thermal rise time of the system. Investigating this phenomenon within a laboratory environment, with a repeatable and simple test is very useful within the design process.
