On the Dynamic Characteristics of Swinging Damaged Rectangular Vessels - An Analysis Employing Collaborative Simulation Based on MATLAB/FLUENT

Abstract:

The existing stability evaluation methods of damaged vessels fell short of the consideration of the turbulent characteristics. Based on the analysis of the coupled relation of the damaged rectangular vessels’ stability and the water dynamic characteristics under different stages, collaborative simulations were made with the aid of MATLAB and FLUENT. Results show that: (1) the swing significantly hinders the turbulent; when the swinging amplitude is comparatively small, its impact is weakened accordingly. (2) When the swinging amplitude increases, in phase , backflow emerges. (3) When the swing frequency is high, an extremum appeared in phase , whose value is determined by the biggest swing angular acceleration.
