An Improved Direct Forcing Immersed Boundary Method for Fluid Structure Interaction Simulations1Source: Journal of Fluids Engineering:;2014:;volume( 136 ):;issue: 004::page 40903DOI: 10.1115/1.4026197Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the present work, we present an improved version of the directforcing immersed boundary (IB) method proposed in Wang and Zhang (2011, “An Immersed Boundary Method Based on Discrete Stream Function Formulation for Twoand ThreeDimensional Incompressible Flows,†J. Comput. Phys., 230(9), pp. 3479–3499). In order to obtain an accurate prediction of local surface force, measures have been taken to suppress the unphysical spatial oscillations in the Lagrangian forcing. A fluidstructure interaction (FSI) solver has been developed by using the improved IB method for the fluid and the finite difference method for the structure. Several flow problems are simulated to validate our method. The testing cases include flows over a stationary cylinder and a stationary flat plate, twodimensional flow past an inextensible flexible filament, and threedimensional flow past a flapping flag. The results obtained in the present work agree well with those from the literature.
