Single Stage Air Compressor Test Rig

Technical Description

A wind tunnel is the classic experiment system for aerodynamic flow experiments. The model being studied remains at rest while the flow medium is set in motion, and thus the desired flow around the model is generated. Open wind tunnel used to demonstrate and measure the aerodynamic properties of various models. For this purpose, air is drawn in from the environment and accelerated. The air flows around a model, such as an aerofoil, in a measuring section. The air is then decelerated in a diffuser and pumped back into the open by a fan. The carefully designed nozzle contour and a flow straightener ensure a uniform velocity distribution with little turbulence in the closed measuring section. The flow cross section of the measuring section is square. The built-in axial fan with guide vane and a variable-speed drive is characterised by an energy-efficient operation at high efficiency. Air velocities of up to 28m/s can be reached in this open wind tunnel. The trainer is equipped with an electronic two-component force sensor.Lift and drag are detected and displayed digitally. The air velocity in the measuring section is displayed on the inclined tube manometer. The tube manometers is recommended for measuring the pressure curves in drag bodies. Extensive accessories allow a variety of experiments, for example lift measurements, pressure distributions, boundary layer analysis or visualisation of streamlines. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.

AIM To find out dryness fraction of steam by combined separating and throttling calorimeter.

PRODUCT DETAILS

The steam passing out from separating calorimeter may still contain some water vapour , in it . in other words it may not be absolutely dry . again , in a throttling calorimeter steam after passing through the throttle valve must be superheated or at least dry saturated . this limits the extent of dryness fraction that can be reliably measured , depend up on the pressure of steam in the main steam pipe . if a sample of steam, which may be still wet after passing through the throttle valve i.e it will not be superheated . thus under this condition the throttling calorimeter fails to enable us in determining the value of dryness fraction of steam . to overcome this difficulties we make use of separating and throttling calorimeter . first the steam is passed through separating calorimeter where itlosses most of it’s moisture and becomes comparatively drier, it is than passed through the throttling calorimeter where super heating takes place with out changr of total heat . the temperature and pressure of steam after throttling are measured by using a thermometer and manometer respectively.

DESCRIPTION

The set up consist of a separating and throttling calorimeter . a steam generator is provided at the base of the apparatus . a thermostat knob is provided at the front of apparatus to control the temperature inside the steam generator . steam from steam generator is passed from separating calorimeter where most of the water partical get separated from steam and then passed to throttling calorimeter where steam get superheated . after that superheated steam passed through heat exchanger to condense the steam.

SAPARATING CALORIMETER

It consist of two concentric chamber , the inner chamber ,and the outer chamber . which communicates with each other through an opening at the top. As the steam discharge through the metal baskets ,which has a large number of holes , the water partical due to there heavier momentum get separated from the steam and collected in the chamber. The comparatively dry steam in the inner chamber moves up and than down aging through the annular space between the two chambers and enters the throttling calorimeter .

THROTTLING CALORIMETER

It consist a narrow throat . pressure and temperature are measured by manometer and thermometer . the steam after throttling process passed through the heat exchanger and condensate is collected .
