We apply the immersed boundary (IB) method to the 3-D parachute problem, which involves an interaction between the flexible, elastic, parachute canopy and the high-speed airflow (relative to the parachute) through which the parachute falls. In order to take into account the effect of mass of both parachute and payload, the penalty immersed boundary (pIB) method is used. We construct a parachute model...
This paper reports the numerical study of the drag of a flexible elastic fiber immersed in a two-dimensional viscous flow using the immersed boundary (IB) method. We found drag reduction of a flexible fiber compared to a stiff one and the drag coefficient decreases with respect to the dimensionless fiber length within a certain range. The results are a starting point for the understanding of the role...
