... for 4 h at two pressure drops. The seal leakage before and after endurance tests was compared. After test, the profile of finger foot was analysed to obtain the seal wear. Figure 1 High-speed seal test rig and sealing unit Finger seal Leakage Wear Experimental test Testing...

... slenderness ratios (L/D) and three clearance ratios. The equations that govern the flow and energy transport are solved by the finite difference method, and the experimental tests are conducted in a test rig of high speed and heavy haul tilting pad journal bearing. The shaft speed ranges from 3,000 to 16,500...
