Steam Nozzle Performance Apparatus with Compressor
Product Code : EL-TELE-10715
Quick Answer: The Steam Nozzle Performance Apparatus with Compressor is an experimental unit that lets students study the performance of a nozzle as either a kinetic energy or thrust producer, and examine the effect of inlet and outlet pressure ratio on mass flow and pressure distribution in the nozzle. Compressed air is supplied to the unit from a laboratory source, and convergent and convergent-divergent nozzles, each designed for a different theoretical expansion ratio, can be changed rapidly. The unit is fully instrumented to measure pressure, mass flow, temperature, thrust, and impact force, so operating conditions can be quickly varied to produce results over a wide range of pressure ratios.
The Steam Nozzle Performance Apparatus with Compressor is an experimental unit that allows students to study the performance of a nozzle as either a kinetic energy or thrust producer, and to study the effect of inlet and outlet pressure ratio on the mass flow and pressure distribution in the nozzle. Compressed air is supplied to the unit from a laboratory source. Convergent and convergent-divergent nozzles are available and can be changed rapidly; these nozzles are designed to operate at different theoretical expansion ratios.
Each nozzle is equipped with axial pressure tappings that can be connected to the 8 panel-mounted pressure gauges, and the Nozzle Performance unit is fully instrumented to measure pressure, mass flow, temperature, thrust, and impact force. The operating conditions can be quickly varied to produce results over a wide range of pressure ratios.
FEATURES:
Visual demonstration of nozzle choking.
Determination of the effect of inlet and back pressure on mass flow rate through nozzles.
Calculation of nozzle efficiencies.
Determination of jet reaction and specific thrust at a range of inlet and backpressures.
Comparison of mass flow rate with theoretical values.
Measurement of the velocity of a jet issuing from a nozzle operating at a variety of inlet and pressure.
SPECIFICATION:
A series of convergent and convergent-divergent nozzles may be installed in one of two locations in a high pressure-measuring chamber.
Standard unit includes convergent – divergent ducts designed to produce at the throat and supersonic velocities downstream.
A pressure regulator, throttle valve and backpressure valve allow the airflow rate, inlet and discharge (or back) pressure to be varied.
Inlet and outlet air pressures, temperatures and airflow rate are recorded by a combination of instrumentation on the Compressible Flow
