F300C Experimental Impulse Turbine Module

F300C Experimental Impulse Turbine Module

The F300C is a small, single stage, axial flow impulse turbine that operates with the F300 Base Unit and 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 F300D.

 

F300C Experimental Impulse Turbine Module

An impulse turbine with 4 separate nozzles and control valves, a throttle valve and  belt brake dynamometer. Inlet and outlet air temperatures are recorded allowing the temperature drop due to work output to be measured.

Inlet and outlet air pressures, temperatures and air flow rate, turbine torque and speed are recorded by a combination of instrumentation on the Compressible Flow Range F300 base unit and the optional module.

Requires the F300 Compressible Flow Range base unit for operation.

  • Visual examination of a small impulse turbine.
  • Production of torque/speed and power/speed curves from a no load speed of approximately 40,000 rev/min to stall and at a range of inlet pressures.
  • Comparison of turbine performance including specific air consumption when using throttle control or  nozzle(4) control.
  • Application of the First law of Thermodynamics to a simple open system undergoing a steady flow process..
  • Determination of the isentropic efficiency of a turbine and plotting the end states on a temperature/entropy diagram.
  • Determination of resisting torques due to bearing friction and  disc aerodynamic friction at various speeds.
