..., it is evident that certain hydrocarbon reactions are present in the probe system, and the CQQ probe can quench those reactions, minimizing sampling loss. To better understand the hydrocarbon chemistry occurring in the sampling system and to draw more affirmative conclusions, more measurements with additional...

... discusses in detail the losses in high speed PM machines. A typical PM machine designed for microturbine application is presented with its detailed loss calculations. Various loss verification methods are also discussed. A spin-down test is a method to measure the damping torque. When the motor is free...

... a formulation of the optimization problem for the late bearing design of a complex rotor-bearing system. Furthermore, the usefulness of the search method is evaluated on a difficult problem. The effects considered are power loss and limiting temperatures in the bearings as well as the dynamics at the system...

... in order to assess the impact on the power consumption. This work is the first part of a survey aiming to reduce power losses in bearing chambers. In the first part, the parameters affecting the power losses are identified and evaluated. Contributed by the Structures and Dynamics Division...

...E. de Villiers; D. G. Kro¨ger The inlet loss coefficients for dry, isotropically packed, circular and rectangular counterflow cooling towers are determined experimentally and empirical correlations are formulated to fit this data. Computational fluid dynamics is used to investigate the dependence...
