RISElliptic Motions and Control of Rotors Suspending in Active Magnetic Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nonlinear dynamics of rotors suspending in the active magnetic bearings (AMBs) with eight pole pairs are investigated. The nonlinear governing equations of two degreeoffreedom (2DOF) are obtained considering the rotor ...
Surface Energy Components and Land Characteristics of a Rice Paddy
Publisher: American Meteorological Society
Abstract: Many meteorological and air-quality models require land characteristics as inputs. A field experiment was conducted to study the surface energy budget of a rice paddy in Taiwan. During the day, the energy balance ratio ...
Multiphysics Coupling Model for Computing Pier Scour upon Simulation and Experiment
Publisher: American Society of Civil Engineers
Abstract: This paper established a laboratory-scale model with multiphysics coupling computation to estimate the scour depth of the pier. The model employed governing equations based on structural dynamics (SD) and fluid–structure ...
Measurements of Aerodynamic Roughness, Bowen Ratio, and Atmospheric Surface Layer Height by Eddy Covariance and Tethersonde Systems Simultaneously over a Heterogeneous Rice Paddy
Publisher: American Meteorological Society
Abstract: The aerodynamic roughness, Bowen ratio, and friction velocity were measured over a rice paddy using tethersonde and eddy covariance (EC) systems. In addition, the height ranges of the atmospheric inertial sublayer (ISL) ...
