abstract = {<p style="text-align: justify;">The interaction between free surface flow and structure is investigated using
a new level set immersed boundary method. The incorporation of an improved
immersed boundary method with a free surface capture scheme implemented in a
Navier-Stokes solver allows the interaction between fluid flow with free surface and
moving body/bodies of almost arbitrary shape to be modelled. A new algorithm is
proposed to locate exact forcing points near solid boundaries, which provides an accurate
numerical solution. The discretized linear system of the Poisson pressure equation
is solved using the Generalized Minimum Residual (GMRES) method with incomplete
LU preconditioning. Uniform flow past a cylinder at Reynolds number Re=100
is modelled using the present model and results agree well with the experiment and
numerical data in the literature. Water exit and entry of a cylinder at the prescribed
velocity is also investigated. The predicted slamming coefficient is in good agreement
with experimental data and previous numerical simulations using a ComFlow model.
The vertical slamming force and pressure distribution for the free falling wedge is also
studied by the present model and comparisons with available theoretical solutions and
experimental data are made.</p>},
