In this article, a numerical meshless method called Weakly Compressible Smoothed Particle Hydrodynamic (WCSPH) is used to simulate the solitary wave breaking process on the beach. The present model is a two dimensional model that considers the fluid weakly compressibility. This model solves the viscous fluid equations to obtain velocity field and density and solves the equation of state to obta...
In recent years reflectarray antennas have received considerable attention due to their unique capabilities. However, due to their large size, analyzing the performance of these antennas using traditional full wave finite-difference and finite-element techniques requires considerable computational resources. In this paper, we present an efficient method to accurately analyze these class of ante...
In this paper a multi-body system of barge type wind turbine under stochastic wave and wind has been modeled within MSC ADAMS. For wind loading, the stochastic turbulent wind data have been extracted using TurbSim software.Also, the AeroDyn module has been used for calculating lift and drag forces on the blades of turbine.. The hydrodynamic loads have been calculated using HydroDyn module withi...
Moving Particle Semi-implicit (MPS) which is a meshless and full Lagrangian method is employed to simulate nonlinear hydrodynamic behavior in a wide variety of engineering application including free surface water waves. In the present study, a numerical particle-based model is developed by the authors using MPS method to simulate different wave problems in the coastal waters. In this model flui...
The application of multidimensional digital ltering theory to the simulation of continuous systems with distributed parameters has been treated in various recent contributions. Here, two diierent concepts will be compared, using a lossy transmission line of nite extent as an example. One approach is based on multidimensional wave digital lters, the other on the derivation of a simulating struct...
abstract according to increase in electricity consumption in one hand and power systemsreliability importance in another , fault location detection techniqueshave beenrecentlytaken to consideration. an algorithm based on collected data from both transmission line endsproposed in this thesis. in order to reducecapacitance effects of transmission line, distributed parametersof transmission line...
Breakwaters have changed a lot during their design history. Overtopping is an important parameter that its evaluation and reduction has always been noticed. In this study, the wave overtopping of composite berm breakwater as a new conceptual structure has been investigated numerical modeling was performed using FLOW-3D software. Then, based on a laboratory model conducted by Losada et al, cali...
The generation mechanism of RX-mode waves in the equatorial plasmasphere has not been well understood. The Akebono passing through the storm time geomagnetic equator shows the possibility of the local enhancement of RX-mode waves in association with intense Z-mode waves in the equatorial region. We use the initial parameters inferred from observational data from around the plasma-wave generatio...
The Gonu tropical cyclone is the strongest storm in the Arabian Sea in which has cause damage in the Iranian south coastlines. The aim of the current paper is to numerically simulate the wave’s characteristics as well as the storm surge during the Gonu event by employing the SWAN wave model and the GETM hydrodynamic model. The simulation duration is one month i.e. from15 May to 15 June 2007. Th...
