1.1 This guide covers techniques and procedures used in defining initial conditions for modeling saturated ground-water flow. The specification of initial conditions is an essential part of conceptualizing and modeling ground-water systems.

1.1 This guide covers the specification of appropriate boundary conditions that are an essential part of conceptualizing and modeling ground-water systems. This guide describes techniques that can be used in defining boundary conditions and their appropriate application for modeling saturated gro...

A wide speed range permanent magnet synchronous generator (PMSG) system is studied in this paper, including the PMSG design and comparative study on control strategies with a pulse width modulation (PWM) rectifier, the purpose of which is to regulate the DC-link voltage. It is of great importance to...

Power electronic zigzag transformer is an attractive solution for the flexible interconnection of smart distribution networks. It is constituted by slow-response and low-precision thyristor converters and fast-response and high-accuracy voltage source converters. This paper models its primary circui...

Large eddy simulations were used to model the three-dimensional flows around a non-submerged spur dike. Based on the rigid lid assumption, all these vortex flows around the spur dike, which probably affected the whole flow field, were numerically simulated and analyzed. The largest circulating flow ...
