Title: | Variation in the Thickness of A Fluid Interface Due to Internal Wave Propagation: A Lattice Boltzmann Simulation | Contributor(s): | Buick, James (author); Hann, DB (author); Cosgrove, JA (author) | Publication Date: | 2004 | Handle Link: | https://hdl.handle.net/1959.11/1442 | Abstract: | The change in the thickness of an interface between two immiscible fluids due to the propagation of an internal capillary-gravity wave along the interface is considered using a BGK (Bhatnagar, Gross and Krook) lattice Boltzmann model of a binary fluid. The vertical thickness of the interface is recorded from the simulations since this is the most easily measured quantity in any simulation or experiment. The vertical thickness is then related to the actual thickness (perpendicular to the interface) which is seen to vary with the phase of the wave. The positions of the maxima and minima thicknesses are seen to be approximately constant relative to the phase of the propagating wave and the range of variation of the thickness decreases at approximately the same rate as the wave amplitude is damped. A simplified model for the interface is considered which predicts a similar variation due to the interface being stretched as the internal wave propagates. | Publication Type: | Journal Article | Source of Publication: | American Journal of Applied Sciences, 1(1), p. 5-11 | Publisher: | Science Publications | Place of Publication: | United States of America | ISSN: | 1554-3641 1546-9239 |
