abstract = {<p style="text-align: justify;">The immersed boundary method has emerged as an efficient approach for
the simulation of finite-sized solid particles in complex fluid flows. However, one of
the well known shortcomings of the method is the limited support for the simulation
of light particles, i.e. particles with a density lower than that of the surrounding fluid,
both in terms of accuracy and numerical stability.<br/>Although a broad literature exists, with several authors reporting different approaches
for improving the stability of the method, most of these attempts introduce extra complexities and are very costly from a computational point of view.<br/>In this work, we introduce an effective force stabilizing technique, allowing to extend
the stability range of the method by filtering spurious oscillations arising when dealing
with light-particles, pushing down the particle-to-fluid density ratio as low as 0.04.
We thoroughly validate the method comparing with both experimental and numerical
data available in literature.</p>},
