Continuously operating supersonic wind tunnel with a rectangular measuring section. Transsonic and supersonic flows from Ma 0.8 up to Ma 1.8 can be realized with interchangeable measuring sections and nozzle profiles. Supersonic flow and the occurring shock waves can be directly observed with the supplied Schlieren optic apparatus. The continuous operation allows enough time to take measurements and to observe the phenomena. Four aerofoil models are supplied: a wedge, a double wedge, a bullet and a rocket. A flow straightener at the inlet ensures a low degree of turbulence.
The tunnel is driven by a speed controlled vacuum pump. The pump is effectively silenced so it can be placed in the same room as the wind tunnel.
The accessory is intended for use with the test stand. A transparent pipe bend with a constant square cross-section is attached to the test stand using quick action fasteners. The pipe bend is equipped with measuring glands at regular intervals for measuring the pressure loss. The measuring gland are connected to the Multi Tube Manometer.
The accessory, in combination with the Air Flow Bench, is suitable for investigations on a pneumatic logic component. The experimental set-up has a transparent front panel that, together with a rear wall, forms a gap that is bounded by swivelling, sliding side walls. A sliding wedge fitted between the guides separates the outlet zone. Scales allow the sliding elements to be precisely adjusted. The logic component is fitted to the test stand using quick action fasteners.
The is part of a series of units that enable experiments to be performed on flow processes with the aid of a computer. In this case experiments can be performed on air flow in conjunction with accessories.
A radial fan generates a flow speed of approx. 9m/s in a horizontal flow section. The inlet funnel ensures that the flow is low in turbulence and thus that the speed distribution in the intake pipe is homogeneous. The unit is equipped with transducers for temperature and pressure. The following accessories are required for operation: Data Logging Unit. To measure the electrical power consumption, the Digital Power Meter is required.
With the, an accessory for the , it is possible to investigate the pipe friction losses in a flow of air for different fittings such as a straight pipe section, an elbow, a bend, and different pipe inlets. The models supplied are made of plastic and are equipped with connections for pressure measurement; these are connected to the Computer Linked Air Flow Bench.
Air Conditioning Lab Equipment Manufacturer
Nozzle Pressure Distribution :
The benchtop unit enables compressible flow in nozzles to be investigated. A wide range of inlet and outlet pressures can be set with a pressure controller and a needle valve. Easily interchangeable nozzle models (one convergent and two convergent-divergent) are equipped with pressure tappings so the pressure distribution along the flow can be determined. Manometers on the front panel indicate the pressures for air inlet and outlet and up to eight pressures in the nozzle. The air inlet and outlet temperatures are measured using thermocouples and displayed digitally. The airflow rate can be determined using a rotameter. The unit is driven with compressed air.
Heat Transfer Lab Equipment Manufacturer
The Heat Transfer Model, designed as an accessory for the , is used for the experimental investigation of heat transfer from a heated rod to an air flow. It comprises a rod oven and a copper specimen. The copper rod is heated in the oven to approx. 110°C, before it is placed in the Computer Linked Air Flow Bench. A temperature sensor is built into the specimen; this is connected to the oven and from there transmits its measured data to the Data Logging Unit. By measuring the cooling curve in a flow of air, the coefficient of heat transfer can be determined.
