For the stability analysis of turbomachinery rotors one must have a knowledge of all forces that might influence the vibrational behavior of rotors. These also include previously insufficiently known flow forces generated in the chambers of labyrinth seals. Within the framework of the present research project, the lateral and resetting forces of va...
Measurements of pressure variations in the source region are to be conducted in conjunction with an investigation of sound generation mechanisms on axial flow turbomachinery. The capacitor microphones normally used in acoustic measuring techniques cannot be used universally because of their volume. In addition, there are plans to measure pressure v...
Laser anemometer surveys were made of the 3-D flow field in NASA rotor 67, a low aspect ratio transonic axial-flow fan rotor. The test rotor has a tip relative Mach number of 1.38. The flowfield was surveyed at design speed at near peak efficiency and near stall operating conditions. Data is presented in the form of relative Mach number and relativ...
