El Plan de Actuación Anual 2013 cuenta con 3.800 millones de euros

El Ministerio de Economía y Competitividad, a través de la Secretaría de Estado de I+D+i, ha publicado el Plan de Actuación Anual 2013, que cuenta con algo más de 3.800 millones de euros entre subvenciones y créditos. Este documento contiene los recursos presupuestarios y el calendario previsto para cada una de las actuaciones de I+D+i a desarrollar durante el año en curso. El Plan, que facilita la participación de los agentes del sistema de I+D+i para competir por las ayudas y conseguir los créditos, describe cada una de las acciones que la Administración General del Estado dispone para financiar la I+D+i....

Lateral Force and Yaw Moment on a Slender Body in Forward and Transverse Motion

J. Offshore Mech. Arct. Eng. 135(3), 031101 (Mar 28, 2013) (9 pages) doi:10.1115/1.4006153 History: Received December 29, 2008; Received May 29, 2011 Ronald W. Yeung, Robert K. M. Seah and John T. Imamura Abstract This paper presents a solution method for obtaining the lateral hydrodynamic forces and moments on a submerged body translating at a yaw angle. The method is based on the infinite-fluid formulation of the free-surface random-vortex method (FSRVM), which is reformulated to include the use of slender-body theory. The resulting methodology is given the name: slender-body FSRVM (SB-FSRVM). It utilizes the viscous-flow capabilities of FSRVM with a... Read More

Experimental Wave Generation and Cancellation With a Cycloidal Wave Energy Converter

30th International Conference on Ocean, Offshore and Arctic Engineering (OMAE), 2011 Siegel, S.; Roemer, M.; Imamura, J.; Fagley, C. & Mclaughlin, T. ABSTRACT We investigate a lift based wave energy converter (WEC), namely, a cycloidal turbine, as a wave termination device. A cycloidal turbine employs the same geometry as the well established Cycloidal or Voith-Schneider Propeller. The main shaft is aligned parallel to the wave crests and fully submerged at a fixed depth. We show that the geometry of the Cycloidal WEC is suitable for single sided wave generation as well as wave termination of straight crested waves using feedback... Read More

Design of Overtopping Wave Energy Convertors for Small Waves

ASME 2010 29th International Conference on Ocean, Offshore and Arctic Engineering. 29th International Conference on Ocean, Offshore and Arctic Engineering: Volume 2 Shanghai, China, June 6–11, 2010 John T. Imamura and Alaa Mansour ABSTRACT This paper proposes a design concept in the area of overtopping ocean wave energy devices. Current models of overtopping devices are limited to locations which experience large wave activity. The high energy associated with large waves enables the ocean water waves to overtop the device ramp into the collection reservoir which discharges through a power generating turbine. The ramp height is necessarily large to establish a... Read More
