...Stefano Ubertini This paper deals with the pressure supply fluctuations that occur in the fuel rail and in the injector on the immediate upstream side of the atomizer. It has been experimentally demonstrated that this has a considerable effect on the instantaneous mass flow and spray velocity thus...

...T. Sattelmayer Gas turbine combustors are often susceptible to self-excited oscillations, which lead to unacceptable levels of pressure, velocity, and heat release fluctuations. Although instabilities can occur in systems with locally constant equivalence ratio, it is very important to take...

... to be small and to arise either during the manufacturing process or as a result of in service wear. The motivation for considering such small variations is that their effects on the forced response of bladed disks can be extremely large, i.e., fluctuations of the blade properties by 1–2% can lead to increases...
