Numerical Simulation of Dam Breaking Using Smoothed Particle Hydrodynamics and Viscosity Behavior
meshless method smoothed particle hydrodynamics (SPH) dam breaking free surface flow
2011/9/9
Smoothed particle hydrodynamics (SPH) is a Lagrangian meshless particle method. It is one of the best method for simulating violent free surface flows in fluids and solving large fluid deformations. D...
Upper Layer Modification at Ocean Station Papa：Observations and Simulation
Upper Layer Modification Ocean Station Papa
2009/4/2
Time-series observations of the upper mixed layer of the ocean are presented for a six-week period at Ocean Station Papa in the northeast Pacific Ocean. These observations indicate the rate and extent...

AUV kinematics model dynamics model motion control simulation
2011/9/9
Accurate modeling and simulation of autonomous underwater vehicle (AUV) is essential for autonomous control and maneuverability research. In this paper, a mini AUV? “MAUV-Ⅱ” was researched and the non...
Two-dimensional, time-dependent, nonlinear, incompressible, viscous flow calculations of realistic models of tsunami waves interacting with continental slopes and shelves were performed. Wave heights ...
A Numerical Simulation of the Onset of El Niño
Numerical Simulation Onset of El Niñ o
2009/3/7
El Niño may be defined oceanographically as a massive influx of warm water into the coastal region of Ecuador and Peru. We have tested the hypothesis that these rare events occur after a substa...
