The Simple Wave Simulator Interactive provides the learner with a virtual wave machine for exploring the nature of a wave, quantitative relationships between wavelength, frequency and speed, and comparisons between transverse waves such as those traveling through a rope and longitudinal waves such as sound. With a little bit of trigonometry (you might want to review your basic trig, especially what sin and cos are), we can think about whether a baseball can clear the "green monster" at Fenway Park. We develop the solution to the 2D acoustic wave equation, compare with. This geometry is depicted for the 2D case in Fig. Learn More. Noriaki MAETANI, Tomoyuki KUROSE, Kenji TSURUTA* Graduate School of Natural Science and Technology Okayama University Okayama 700-8530, Japan The lens effect of acoustic waves in a two-dimensional (2D) phononic crystal is studied by numerical simulation based on the finite-difference time-domain (FDTD) method. Deadline: Oct 13; Each student delivers a set of files, including a project report, in her/his GitHub repo, but we encourage collaboration. “Basal waves” – still a sine wave-based simulation of ocean waves, but with physical characteristics constrained to match real-world waves; 2. The waves spread out from two sources oscillating with the same phase. Welcome to the SWASH home page: SWASH is a general-purpose numerical tool for simulating unsteady, non-hydrostatic, free-surface, rotational flow and transport phenomena in coastal waters as driven by waves, tides, buoyancy and wind forces. The links below contain animations illustrating acoustics and vibration, waves and oscillation concepts. This app shows the interference of two circular respectively spherical waves (e. The second two simulations use a broken wave. Simulation of waves using Finite Difference Method (FDM) and Preconditioned Conjugate Gradient (PCG) method as a solver of linear systems. wave potential in the magnetosphere and U•4sa is the wave potential in the magnetosheath. Quantum 3D ™ provides a set of models for simulation of the various effects of quantum confinement and quantum transport of carriers in semiconductor devices. Module Time: 6 hours and 50 minutes. se Bachelor's Thesis at NADA Course: DD143X. The wave code has been successfully applied to describe low frequency waves in planetary magnetospheres (i. This process has previously been shown in numerical simulations to decrease the plasma reflectivity due to stimulated Brillouin scattering. This paper presents the integration of a two-dimensional (2D) model with ISIS to enhance its capability for simulating floodplain flows. The properties of an idealized drumhead can be modeled by the vibrations of a circular membrane of uniform thickness, attached to a rigid frame. Make a Splash With Dynamic 2D Water Effects There are two mostly independent parts to the water simulation. The k-Wave toolbox is a powerful tool for general acoustic modelling. Study the motion of waves on a string and the effect of tension, density and damping upon their behavior with the Slinky Lab Interactive. When computing an electromagnetic (EM) wave propagation and resonance analysis, to address the increased computational cost for larger antennas, the latest version of COMSOL’s Multiphysics® software exploits 2D axisymmetric modeling, using a technique available in the. background horizontal wind component in the direction of the wave vector and is the mountain peak height. It uses the Courant-Friedrich-Levy stability condition.
