Allows students to study the performance of a nozzle as either a kinetic energy or thrust producer.
Operating from a normal laboratory compressed air supply the unit is supplied with one convergent and four convergent-divergent nozzles that can be rapidly interchanged. These nozzles are all designed to operate at different theoretical expansion ratios. The 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.
F810 Nozzle Pressure Distribution Unit
Enables
students to study the effect of inlet and outlet pressure ratio on
the mass flow and pressure distribution in nozzles.
Operating from a normal laboratory compressed air supply the unit is
supplied with one convergent and two convergent-divergent nozzles of
identical throat diameter. These nozzles can easily be interchanged
and 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.The unit is
fully instrumented to measure pressures, mass flow and temperatures
over a wide range of pressure ratios.
Together, the Nozzle Performance Test Unit F791 and the Nozzle Pressure Distribution Unit F810 provide all of the basic nozzle laboratory experiments for compressible fluids.
F800 Experimental Impulse Turbine
A small, single stage, axial flow impulse turbine that operates on the
compressed air supply usually available in laboratories. Instrumentation
is provided to measure the air supply pressure, mass flow rate and
temperature as well as the turbine speed and torque.
The turbine may be operated from stall to a no-load speed of up to
50,000rpm and turbine performance studied using either throttle or
nozzle control. At a fraction of the overall cost, this unit
demonstrates all the characteristics of an impulse turbine that are
normally studied using a large steam power plant. The unit is
complementary to the Experimental Reaction Turbine.
A small, single stage, radial flow reaction turbine that operates on the compressed air supply usually available in laboratories. Instrumentation is provided to measure the air supply pressure, mass flow rate and temperature as well as the rotor torque and speed.
The turbine may be operated from stall to a no-load speed of 35,000rpm and classic turbine performance curves can be generated.
The unit is complementary to the Experimental Impulse Turbine.
Incorporating all the major components and exhibiting all the performance characteristics for a fraction of the capital and running costs of a typical steam power plant, the unit operates on the classic Rankine cycle using a refrigerant as the working fluid.
Instrumentation includes all relevant system pressures and temperatures, turbine torque and speed, working fluid and cooling water flow rates.
Supplied in standard form with an electric heat source, an optional set of Solar Panels and Installation Package is available to demonstrate the generation of work from solar radiation.
The Solar/Heat Source Vapour Turbine and the Vapour Jet Refrigerator/Heat Pump may be operated from any source of hot water at approximately 90°C. In locations where conditions are suitable, the Solar Panels and Installation Package enables these units to be operated using hot water generated from solar radiation.
The Package, which is designed for on site assembly and installation, includes the solar panels, additional instrumentation and all components necessary to connect to the couplings on the above mentioned units.
