Numerical Simulation Analysis of the Impact of Baffles on Liquid Sloshing in Hazardous Chemical Tankers during Braking
摘要
Abstract
Research on the suppression of liquid sloshing in hazardous chemical tankers during braking is currently limited,and there are no unified standards for the design and use of internal baffles.To explore these issues,a tank model for hazardous chemical tankers was established,and finite element analysis(FEA)was performed using the ANSYS software.This enabled numerical simulations of the liquid slosh impact of various liquid media,as well as the evaluation of liquid slosh impact in tanks without baffles and with three common baffles(Types A,B,and C).Additionally,a standardized parameter was introduced--the baffle area ratio(defined as the ratio of perforated area to solid baffle area)--to investigate the quantitative relationship between the baffle's perforation characteristics and its anti-sloshing performance.The results reveal that,under the same external excitation,the density of the liquid medium significantly influences the maximum sloshing impact.Specifically,when the liquid density exceeds 740 kg/m³,the peak sloshing impact increases with the density.The installation of baffles reduces the impact stress on the tank's front head.As the baffle area ratio decreases,the maximum impact force exerted on the tank shows a noticeable decreasing trend.When the baffle area ratio falls within 0.15-0.5,the maximum impact force on the tank is minimized,and the effect of liquid sloshing on the tank is reduced.The C-type baffle(with a baffle area ratio of 0.25)was found to be the most effective in suppressing liquid sloshing.It is recommended to prioritize the use of C-type baffles in practical applications or to maintain a 0.15-0.5 baffle area ratio to effectively reduce the impact of liquid sloshing.关键词
