Air Flow and ThermodynamicsTray Dryer
This is a basic unit for studying of tray drying by hot air.
The unit consists of a rectangular duct. Air is drawn into the duct by an axial flow fan at the front end of the duct. Fan speed is adjustable. A bank of electric heaters behind the fan raises air temperature. Behind the heater is a drying compartment with transparent access door. A rack of trays is suspended from a balance above the duct. Temperatures and humidity before and after the drying trays are measured.
Instruction manual is also included.

Air Flow and ThermodynamicsTwo-Shaft Gas Turbine
The turbine is a small two-shaft gas turbine engine with a radial flow compressor and axial flow turbines as in the modern gas turbine power plant.
The first shaft is a hot gas generator. Inlet air through an orifice flow measuring device is compressed by a single stage radial flow compressor. The turbine is motor started and runs on Jet A fuel. Fuel is injected by a fuel pump and ignited in the combustion chamber providing hot gas for a single stage axial flow turbine which inturn drives the compressor. The hot gas is discharged axially to a larger power turbine on the second shaft and exhausts to atmosphere. A fan is provided for cooling the gear box.
Speed of the power turbine is reduced by the gear box. A water brake absorber is connected to the gear box for power measurement. The brake requires outside water supply. Load is manually controlled.
An Electronic Control Unit (ECU) controls the basic turbine operation. Additional instruments are provided for monitoring and controlling turbine performance.
A touch screen computer with an interface unit and software are provided for speed and load control, data display and analysis, and to assist the ECU.
