A floating oscillating water column (OWC) wave energy converter (WEC) supported by mooring lines can be modelled as an elastically OWC. The main objective of this paper is to investigate the effects frequency ratio on performance OWC (oscillating column) devices that oscillate either vertically or horizontally at two different mass ratios (m = 2 and 3) through two-dimensional computational flui...

There is a vast amount of energy available in ocean waves which can contribute to provide the electricity supply specially for countries surrounded by ocean. This paper provides background knowledge different techniques harness kinetic and potential wave power along with an overview recent developments Oscillating Water Columns Wave Energy Converters. The main purpose this study thorough review...

in order to simulate the rotating disk contactor all hydrodynamic parameters, dispersed phase hold-up, characteristic velocity, mean drop size, drop size distribution, axial mixing and mass transfer have been taken into account. mechanisms of mass transfer (stagnant, circulating, oscillating drops) were used in this study. column height found from effect of mean drop size and drop size distribu...

Abstract: Linear time-varying systems driven by periodic input signals are ubiquitous in control systems. For various reasons, including disturbance rejection and diagnosis by analysis of the trajectories, estimation of their input signals is often desirable. In the present paper, we illustrate a recently proposed general method to solve such problems by an asymptotic reconstruction of the Four...
