An Experimental Investigation on the Misalignment Effects in Journal Bearings
TL;DR: In this paper, the experimental performance of misaligned cylindrical and three-lobe journal bearings was evaluated using a double-disc rotor system with a test bearing in the middle and driven by a variable speed DC motor through an electromagnetic coupling.

Drag reduction fundamentals
TL;DR: In this paper, the effects of dilute solutions of linear, random-coiling macromolecules in turbulent pipe flow is reviewed. And the experimental evidence is emphasized in three sections concerned with the graphical display of established features of the phenomenon, data correlation and analysis, and the physical mechanism of drag reduction.

Drag reduction in rough pipes
TL;DR: In this paper, the impact of dilute, distilled water solutions of four polyethylene-oxides and one polyacrylamide, molecular weights respectively 0·1 × 106 to 8 × 106 and 13 × 106, was studied experimentally in one smooth and three sand-roughened pipes, relative roughnesses (R/k) 15, 23, 35, all of about 0·34, in inside diameter.
