摘要
采用开源计算流体力学软件包OpenFOAM,通过质量源造流方程的推导、源区参数设计以及数值水槽边界条件的改进,成功开发了一种基于质量源法的域内源造流数值水槽sklec-Foam.该模型被用于探讨恒定流和非恒定流的生成效果,并与理论值以及olaFlow模型的边界造流法进行了比较.结果表明,基于质量源法的数值水槽模型在造流的精度和稳定性方面表现出色.这一模型为海岸水动力-结构物相互作用研究以及潮滩的保护和服务功能提升提供了科学支撑.
Abstract
Utilizing the open-source computational fluid dynamics software package OpenFOAM,a numerical flume sklec-Foam with in-domain source flow generation based on the mass source method was successfully developed through the derivation of the flow generation equations with mass sources,design of source area parameters,and enhancement of numerical flume boundary conditions.This model was employed to examine the creation of constant and non-constant flows and compared with theoretical values and boundary flow generation method of the olaFlow model.The results indicated that the numerical flume model based on the mass source method performed outstandingly in terms of flow generation accuracy and stability.The model provides technical support for the study of coastal hydrodynamics-structure interaction and the enhancement of preventive and service functions of tidal flats.
