Lunge-feeding in rorqual whales represents the largest biomechanical event on Earth and one of the most extreme feeding methods among aquatic vertebrates. By accelerating to …
Ground vehicle drag coefficient is herein obtained using an unconventional on-road test in real scale. At low-Re numbers, and as a function of velocity variations, transition introduces …
In this study, we experimentally examine the behavior of a free falling rigid sphere impacting normally onto, and penetrating into a quiescent liquid pool. Parameters, which are varied …

THE opening shock factor Ck is a nondimensional ratio corresponding to the maximum drag force Fmax generated by an inflating parachute (Fig. 1). This ratio is expressed in terms of …

This paper discusses the definition and validation of an upgraded model of slider-reefed parafoil inflation. Unlike an early version which focused only on the slider-descent phase …

The Bi-model aims at simulating the inflation of low-porosity, but apex-vented flat-circular canopies. The most important feature of the model involves the use of CFD to obtain canopy …

AS documented in [1], the momentum–impulse theorem (or “MI theorem”) is a very useful tool for analyzing parachute inflation, given that the duration of the net drag force generated …

BECAUSE of its inherent complexity, the modeling of parachute inflation has been most successful, in terms of fidelity and predictive power, when formulated not only for specific …
