... at the middle locations of the two microphones, the present method allows the acoustic velocity, the acoustic mass flux, and the specific acoustic impedance to be determined along the fuel tubing or an air pipe. acoustic waves combustion fuel systems nozzles time-varying systems vortices...

... inequalities time-varying systems Structural dynamics are an important consideration in the design of rotating machinery. Dynamic performance will generally be assessed in terms of machine vibration levels and stability. Optimization of a structural design within the constraints imposed by machine...
