Flow past a sphere at the free-surface using URANS

Flow past a sphere at the free-surface using URANS
The flow past a sphere located at the free-surface, was studied over the critical Reynolds number range: 2x10^5 to 4x10^5. Experiments were carried out in the Lamont tank at the University of Southampton. Due to the inclusion of a free-surface, the solver interFoam (version OF-2.2.0) was used to simulate the flow past the sphere with a Courant number of 1.2 to allow the simulations to run faster without compensating on the results’ accuracy. Maximum wave resistance occurs when the sphere is half-submerged due the maximum crosssectional area of the sphere. The wave resistance component becomes negligible at an immersion depth greater than 175%D.

Abstract

The flow past a sphere located at the free-surface, was studied over the critical Reynolds number range: 2x10^5 to 4x10^5. Experiments were carried out in the Lamont tank at the University of Southampton. Due to the inclusion of a free-surface, the solver interFoam (version OF-2.2.0) was used to simulate the flow past the sphere with a Courant number of 1.2 to allow the simulations to run faster without compensating on the results’ accuracy. Maximum wave resistance occurs when the sphere is half-submerged due the maximum crosssectional area of the sphere. The wave resistance component becomes negligible at an immersion depth greater than 175%D.
