Research and Optimization Design of Liquid Sloshing with Porous Baffle in Complex Connection Tank

液体晃荡通常发生在装有液体的储液箱中,是一种常见的物理现象。在工程结构逐渐复杂化与大型化的趋势下,液体晃荡问题在工程领域中的重要性日渐提高,并介绍了液体晃荡问题的研究现状和发展趋势。本文提出了采用比例边界有限元法(SBFEM)来研究复杂液箱内液体晃荡特性,通过添加格栅的方式来减轻晃荡,并研究不同形式的格栅减轻液体晃荡的程度。此方法具有计算效率高、计算精度高等优点,在液体晃荡问题的研究中具有广泛的应用前景。

Liquid sloshing is a common physical phenomenon that typically occurs in liquid storage tanks.With the trend towards increasingly complex and large-scale engineering structures,the importance of liquid sloshing problems in the field of engineering is growing.This article introduces the current research status and development trends of liquid sloshing problems.SBFEM is proposed to study the characteristics of liquid sloshing in complex liquid tanks.The addition of grids is used to mitigate sloshing,and the degree of sloshing reduction using grids of different forms is studied.This method has the advantages of high computational efficiency and accuracy,and has broad application prospects in the study of liquid sloshing problems.
