Accuracy of Sediment Flux Computations in Tidally Driven Simulations
Publisher: American Society of Civil Engineers
Abstract: Tidal asymmetry, generated by nonlinear shallow water processes, controls to a large extent the long-term fate of noncohesive sediments in estuaries and lagoons. Since the accurate reproduction of this asymmetry is still ...
Case Study: Promoting the Stability of the Óbidos Lagoon Inlet
Publisher: American Society of Civil Engineers
Abstract: The stabilization of tidal inlets by jetties interrupts the littoral drift and has negative visual impacts. This paper proposes an innovative solution to improve the stability of a tidal inlet (the Óbidos Lagoon, Portugal) ...
A Two-Dimensional Methodology to Predict Vertical Axis Wind Turbine Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An accurate two-dimensional methodology, the COIN Lambda Fast Solver, for the computation of the flow field about a vertical axis wind turbine is presented. Such a technique determines the ...
Automatic System for Wind Turbine Testing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An innovative electronic system for testing the performance of wind turbines is presented. The main goal of the system is to increase the accuracy in the measurements of torque and speed for ...
A Finite Element Method for Three-Dimensional Analysis of Thermo-acoustic Combustion Instability
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method for predicting the onset of acoustically driven combustion instabilities in gas turbine combustor is examined. The basic idea is that the governing equations of the acoustic waves can ...
A Modular Code for Real Time Dynamic Simulation of Gas Turbines in Simulink
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A high-fidelity real-time simulation code based on a lumped, nonlinear representation of gas turbine components is presented. The code is a general-purpose simulation software environment useful ...
Mass Balance in Eulerian-Lagrangian Transport Simulations in Estuaries
Publisher: American Society of Civil Engineers
Abstract: This paper investigates the generation of flow mass errors in finite-element shallow water models and the effect of these errors in the mass conservation of Eulerian-Lagrangian transport simulations. Flow mass errors are ...
