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

Scientia Iranica, 2017
The present paper focuses on the assessment of turbulent effects on the impact force, spray, and secondary impact force of the wedge water entry. For this purpose, a finite element based finite volume method code coupled with volume of fluid has been developed. The k-e method has also been implemented to model the turbulence effects. The developed code
