    Lattice Boltzmann modeling of interfacial gravity waves (1998)
    [S.l.] : American Institute of Physics (AIP)

    Notizen: A novel numerical technique for simulating interfacial gravity waves is considered. The model comprises an immiscible, binary fluid lattice Boltzmann model incorporating a gravitational interaction and simulates two immiscible, viscous fluids of different densities with a sharp interface between them. The model is described and the accuracy of the technique is considered. Simulation results are presented and the wave velocities, the oscillation frequency and the damping rate are found and compared to theory. A good comparison is found suggesting that the lattice Boltzmann approach is indeed accurately mimicking the wave dynamics. © 1998 American Institute of Physics.

    Investigation of a lattice gas model for surface gravity waves (1997)
    [S.l.] : American Institute of Physics (AIP)

    Notizen: A recently proposed lattice gas model for simulating surface waves at a free boundary is described in detail. Simulated waves are compared to linear theory and are seen to compare well, provided an additional parameter ε is introduced. This parameter, ε, is investigated and found to be required due to the density gradient produced across the fluid by the gravitational interaction. Its value and the values of the other model parameters are found for a range of gravitational strengths. © 1997 American Institute of Physics.

    Notizen: Internal waves are modelled in two different circumstances: in a continuously stratified fluid and at the interface between two immiscible fluids. This is done using the lattice gas approach. The standard single phase model and an immiscible two-phase model are both modified to incorporate gravitational interactions. Standing internal waves are set up in both models and are seen to oscillate under the action of the gravitational interaction. The results obtained suggest that the lattice gas approach can be a useful tool in the modelling of such phenomena. © 1998 John Wiley & Sons, Ltd.

    SIMULATION OF WAVE MOTION USING A LATTICE GAS MODEL (1996)

    Notizen: The lattice gas model for simulating two-phase flow, proposed by Appert and Zaleski, has been modified by the introduction of gravitational interactions and the new model has been used to simulate standing wave patterns on the free surface of a fluid. The results compare well with linear theory.
