Parametric study on the water impacting of a free-falling symmetric wedge based on the extended von Karman's momentum theory
Yujin Lu, Alessandro Del Buono, Tianhang Xiao +4
The present study is concerned with the peak acceleration azmax occurring during the water impact of a symmetric wedge. This aspect can be important for design considerations of sa…
On applicability of von Karman's momentum theory in predicting the water entry load of V-shaped structures with varying initial velocity
Yujin Lu, Alessandro Del Buono, Tianhang Xiao +3
The water landing of an amphibious aircraft is a complicated problem that can lead to uncomfortable riding situation and structural damage due to large vertical accelerations and t…
Hydrodynamic analysis of the water landing phase of aircraft fuselages at constant speed and fixed attitude
Emanuele Spinosa, Riccardo Broglia, Alessandro Iafrati
In this paper the hydrodynamics of fuselage models representing the main body of three different types of aircraft, moving in water at constant speed and fixed attitude is investig…
Formulations of Hydrodynamic Force in the Transition Stage of the Water Entry of Linear Wedges with Constant and Varying Speeds
Xueliang Wen, Peiqing Liu, Alessandro Del Buono +2
There is an increasing need to develop a two-dimensional (2D) water entry model including the slamming and transition stages for the 2.5-dimensional (2.5D) method being used on the…
A noise reduction method for force measurements in water entry experiments based on the Ensemble Empirical Mode Decomposition
Emanuele Spinosa, Alessandro Iafrati
In this paper a denoising strategy based on the EEMD (Ensemble Empirical Mode Decomposition) is used to reduce the background noise in non-stationary signals, which represent the f…
Experimental Investigation of the Fluid-Structure Interaction during the Water Impact of Thin Aluminium Plates at High Horizontal Speed
Emanuele Spinosa, Alessandro Iafrati
The water impact of an inclined flat plate and at high horizontal velocity is experimentally investigated with focus on the fluid-structure interaction aspects. Several test condit…
Water entry and exit of 2D and axisymmetric bodies
Alessandro Del Buono, Giovanni Bernardini, Alan Tassin +1
The present paper is dedicated to the development of a numerical model for the water impact of two-dimensional (2D) and axisymmetric bodies with imposed motion. The work is a first…
On algebraic TVD-VOF methods for tracking material interfaces
Sergio Pirozzoli, Simone Di Giorgio, Alessandro Iafrati
We revisit simple algebraic VOF methods for advection of material interfaces based of the well established TVD paradigm. We show that greatly improved representation of contact dis…
Cavitation and ventilation modalities during ditching
Alessandro Iafrati, Silvano Grizzi
The flow taking place in the rear part of the fuselage during the emergency landing on water is investigated experimentally in realistic conditions. To this aim, tests on a double…
A fully nonlinear iterative solution method for self-similar potential flows with a free boundary
Alessandro Iafrati
An iterative solution method for fully nonlinear boundary value problems governing self-similar flows with a free boundary is presented. Specifically, the method is developed for a…
Modulational instability, wave breaking and formation of large scale dipoles in the atmosphere
A. Iafrati, A. Babanin, M. Onorato
In the present Letter we use the Direct Numerical Simulation (DNS) of the Navier-Stokes equation for a two-phase flow (water and air) to study the dynamics of the modulational inst…
