... and should be analyzed at the stage of experimental studies planning. This paper presents a study on the accuracy of HTC determination when the external cooling of the bearing chamber is used to obtain the temperature difference sufficient for measurement. Three ways to reduce the relative error of the HTC...

...Abstract Abstract Even though the analytical aspects of the torsional response of a rotor system are straightforward, actually measuring the torsional response has been historically very difficult and therefore somewhat neglected. It is recognized that dynamic torsional stresses can contribute...
