"Design of Ring Cam Pistons for a Low Speed Digital Displacement ® Pump"

Abstract

The advent of Digital Displacement® Technology as a competitive transmission option in the off shore wind industry has led to the requirement for rapid growth in the capacity of hydraulic machinery. Artemis Intelligent Power (AIP) is working with its parent company, Mitsubishi Heavy Industries (MHI), to develop a complete digital displacement transmission for a 7MW wind turbine named Sea Angel. A core component of this work is the development of the low speed Digital Displacement® Pump (DDP®). This presentation will describe the design of ring cam pistons required by the DDP®. In order to meet the displacement requirements of the 7MW wind turbine, whilst keeping the number of components to a minimum, these pistons need to be scaled up beyond any existing design. The non-linear elasto-hydrodynamic scaling of these parts will be the focus of the presentation.

Biography

Henry Dodson graduated from the University of Edinburgh in 2010 having studied Mechanical Engineering with Renewable Energy. In September of the same year he started work at Artemis Intelligent Power as a research and development engineer specialising in Digital Displacement® ring cam pumps. In July 2013 he joined the IES as a PhD student under Dr. John Chick.

"Computational Fluid-Structure Dynamics in Biomimetic and Marine Renewable Technology"

Abstract

In this talk, the research work currently being performed in a CFD research group at NAOME department in the Strathclyde University will be introduced. Particular interests will focus on the investigation for bio-inspired swimming fish and flapping wing using a numerical modelling method. This will further extend to the recently developed industrial biomimetic applications in renewable energy devices. Other CFD and CSD studies in offshore engineering will be described, such as the dynamics response of floating offshore structure and rigid/flexible riser Vortex Induced Vibration.
