Boussinesq Modeling of Alongshore Swash Zone Currents

2004
Abstract : The long-term goal of the study is to develop and integrate numerical models for the understanding and prediction of nearshore processes. The focus of the project is to develop the capability of modeling alongshore swash currents under field conditions based on Boussinesq-type formulations and field observations.

Modelling of sediment movement in the surf and swash zones

Acta Oceanologica Sinica, 2015
Under the action of marine currents, non-cohesive sediments evolve by bed-load, by saltation or suspension depending on their granulometry. Several authors have considered that the movement of sediment is bidimensional and modelized the effects of swell by a constant velocitynear the seabed.

New Swash Plate Damping Model for Hydraulic Axial-Piston Pump

Journal of Dynamic Systems, Measurement, and Control, 1999
A new, open-loop, reduced order model is proposed for the swash plate dynamics of an axial piston pump. The difference from previous reduced order models is the modeling of a damping mechanism not reported previously in the literature. An analytical expression for the damping mechanism is derived.

Swash Zone Dynamics: Modeling and Data Analysis

2003
Abstract : The goals of the work are to develop improved predictive capability for non-linear time-dependent dynamics in the swash zone. The work involves numerical computations, comparison with field and laboratory results, and theoretical analysis. The focus of the project is to quantify net onshore-offshore swash zone properties from Computational ...

Modelling and control of swash-plate dynamics

2008
There are many new examples of applications of hydrostatic transmissions in the mobile scope. Beside the efficiency, the control ability and the fast response of the hydrostatic transmission are very important in modern applications. In this regard, a DC servomotor can be applied as an actuator of the variable displacement mechanism of smaller ...

Design and analysis of the integrated linear actuation module of the swash plate for piston pump/motor

Journal of Physics: Conference Series
To improve the linearity and efficiency of the displacement adjustment of the piston pump/motor, an integrated linear actuation module of the swash plate is proposed in this paper. First, four symmetrical hydraulic cylinders and two racks are designed to

Analytical Modeling and Simulation of a Swash Plate Pump/Motor

SAE Technical Paper Series, 2008
<div class="htmlview paragraph">This paper presents a computer generated model of a hydraulic circuit that is typically seen in hybrid hydraulic vehicles (HHV's). HHV's have shown considerable potential for increasing fuel economy and decreasing emissions for mid-size and commercial trucks that exhibit urban driving habits. The aim of the present
