Abstract: The paper presents several examples of vibrational problems recently experienced by several turbine manufacturers. These problems include stability, system critical speeds, rotor response to unbalance, ...

Abstract: Active commuting to school has decreased in the last decades, replaced by motorized transportation and especially by the car. Beyond the environmental factors, the schools' territorial policies explain this trend. Drawing ...

Abstract: This paper compares heat transfer measurements from a preswirl rotor–stator experiment with three-dimensional (3D) steady-state results from a commercial computational fluid dynamics (CFD) code. The ...
