内容記述 | Physical conditions of free surface were numerically studied in terms of a thermodynamic effect on surface tension and a viscous effect by turbulence on the momentum balance, for a non-compressible fluid flow. A pool-swell experiment performed by Laurence Livermor Laboratory was employed and analyzed for this study. The basic physical model used consists of two-dimensional fluid flow equations similar to those of the SOLA computer program where the location of free surface is calculated using the VOF method. It is concluded from the analyses that the viscous effect of turbulence, as well as the surface tension, plays an important role in free surface calculation and might contribute to stable numerical analyses of free surface fluid flow. On the other hand, the effect of thermodynamics on surface tension calculation is negligible. | |||||
