This paper provides some recent results obtained in the development of Immersed Boundary (IB) methods at the Politecnico di Bari: in particular, the development and testing of one such method—using a versatile Moving Least Squares approach, coupled with a very efficient solver for solving fluid-structure interaction problems in incompressible laminar flows—will be addressed. Such a method allows one to solve complex three-dimensional solid-fluid interaction problems within reasonable computer times. The solver is validated versus: the free fall of a sphere within a fluid at rest and jellyfish propulsion. Such results demonstrate the accuracy, efficiency, and versatility of the proposed method.

This paper provides some recent results obtained in the development of Immersed Boundary (IB) methods at the Politecnico di Bari: in particular, the development and testing of one such method—using a versatile Moving Least Squares approach, coupled with a very efficient solver for solving fluid-structure interaction problems in incompressible laminar flows—will be addressed. Such a method allows one to solve complex three-dimensional solid-fluid interaction problems within reasonable computer times. The solver is validated versus: the free fall of a sphere within a fluid at rest and jellyfish propulsion. Such results demonstrate the accuracy, efficiency, and versatility of the proposed method.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
