MEMS Pressure sensors work on the principle of mechanical bending of thin diaphragm under applied load over diaphragm area. The sensitivity of diaphragm is crucial to efficiency of the sensor. It is defined as the increase in deflection of diaphragm as a result of increase in pressure ... Per saperne di più
Combustion instability has been a serious issue through the developmental history of gas turbine augmentors. When heat release rate oscillations occur in phase with resonant chamber acoustic modes, a feedback cycle is formed in which the strength of local heat release rate and chamber ... Per saperne di più
