Analysis of the Staggered and Fixed Cavitation Phenomenon Observed in Centrifugal Pumps Employing a Gap Drainage Impeller
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Previous work has shown that the employment of a gap drainage impeller in a centrifugal pump can improve the pump's hydraulic performance and cavitation resistance. However, during experiments, an unconventional cavitation ...
Influence of Current Velocity on Wave-Current Forces on Coastal Bridge Decks with Box Girders
Publisher: American Society of Civil Engineers
Abstract: In this paper, a two-dimensional (2D) model for wave-current girder interactions is established to investigate the effect of wave-current forces on box girder bridges. Reynolds averaged Navier-Stokes (RANS) equations ...
Robust Constrained Trajectory Tracking Control for Quadrotor Unmanned Aerial Vehicle Based on Disturbance Observers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a trajectory tracking control scheme for a quadrotor unmanned aerial vehicle (UAV) under unknown external disturbance and input saturation is developed. This scheme includes the position control system and ...
Hierarchical Lateral Planning With Minimum Curvature Peak for Autonomous Vehicles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study focuses on the lateral safety of autonomous vehicles. The aim is to provide greater safety margins for the motion controller under hazardous conditions by improving the planning methods. The proposed lateral ...
