Numerical Assessment of turbulence effect on Forces, Spray parameters, and secondary impact in wedge water entry problem using k-ε method

“…Other researchers who chose laminar assumptions include Khabakhpasheva and Korobkin [13], Yamada et al [14], Alaoui and Neme [15], and Luo et al [16]. On the other hand, other researchers who have conducted a turbulent simulation include Yang et al [17][18][19], Feizi Chekab et al [20], Ghadimi et al [21,22], Farsi and Ghadimi [23][24][25], and Viviani et al [6].…”

Hydroelastic analysis of surface piercing hydrofoil during initial water entry phase

“…He investigated the symmetric oblique wedge studied by Cox [15] and provided the pressure curves and free surface patterns. However comparison of URANS based simulations of Ghadimi et al [16][17][18] with analytical method by Ghadimi et al. [19], SPH simulations by Farsi and Ghadimi [20][21][22], and the conducted study by Feizi Chekab et al [23] showed that consideration of the effects of fluid viscosity for modeling the arbitrary object's water entry, improves the accuracy of water impact characteristics.…”

Asymmetric Water Entry of Twin Wedges with Different Deadrises, Heel Angles, and Wedge Separations using Finite Element Based Finite Volume Method and VOF

“…Circular cylinders have been investigated by Greenhow (1988), Zhu (2006), and Ghadimi et al (2012), while arbitrary sections have been studied by Ghadimi et al (2013Ghadimi et al ( , 2014. Meanwhile, the smoothed particle hydrodynamics method (SPH) has also been used to analyze the wedge water entry problem by Farsi and Ghadimi (2013, 2014a, and 2014b.…”
