  • Introduction Of Residual Stresses To Enhance Fatigue Performance In The Initial Design (.pdf)
    the fatigue conditions at. the trailing edge of a 1st stage low pressure compressor vane to. provide optimal trailing edge damage tolerance. The use of. finite element modeling, linear elastic fracture mechanics, and. x-ray diffraction documentation of the residual stress field to. develop LPB
  • Pressure Transducer Use for Controlling the Superheat in Clean Room HVAC and Refrigeration Systems
    . The refrigeration cycle is as follows: Cool, low-pressure gaseous refrigerant enters the compressor. Hot, high-pressure gaseous refrigerant leaves the compressor and enters the condenser. Hot, high-pressure gaseous refrigerant in the condenser releases heat to the outside environment. Warm
  • Is variable speed drive the panacea we're looking for?
    ). Custom-made compressed air system concepts. During design of a customised compressed air system, the low. pressure swing of only ± 0.1 bar that can be achieved is put to. good use. This can only be achieved, however, with sufficient. buffer volume. Fluctuations in air consumption that do not. exceed
  • Infrared Thermography Program at a Gas-fired Turbine Generation Plant
    to a. GE aero derivative LM6000 PC gas turbine engine. The Gas Turbine Generator (GTG) is the land equivalent of the same engine that is mounted on. the wing of a DC-10 aircraft. The engine has two compressor stages; 5-stage low-pressure compressor. and 14-stage high-pressure compressor. After
  • Piston/diaphragm pressure switches
    diaphragms are compatible with a wider variety of oils but are too stiff at low temperatures to work well in the cold. Older pressure switches targeting shop air and similar low-pressure tasks sometimes used only a flexible diaphragm as a sensing element. These devices had problems handling overpressures
  • ABCs of Refrigeration Pressure Sensing
    the same basic principles of refrigeration. In each system, pressure sensors are vital in controlling the refrigeration cycle and keeping the system efficient. The basic refrigeration cycle is a fourstep process. Low-pressure refrigerant vapor enters the compressor where the volume is compressed
