A modified ALE method for fluid flows around bodies moving in close proximity
A modified ALE method for fluid flows around bodies moving in close proximity is developed and presented. It is developed for 2D moving objects in close proximity of a symmetry plane. Spurious oscillations at higher Reynolds numbers for flapping wings are studied. The modified ALE method shows a reduction in spurious oscillations at higher Re. The modified ALE method has a lower mesh requirement than a typical IBM.
