摘要：
In the basic of peridynamic theory，the peridynamic differential operator was used to solve the fluid continuity equation and momentum equation，and the peridynamic model of two-dimensional viscous fluid motion was established． The fluid was assumed to be weakly-compressible．The applicability of the established fluid calculation model in internal flow，free surface flow and flow around the cylinder was verified by three classical examples of two-dimensional cavity drive，dam break and low Reynolds number cylinder flow，and compared with the existing experimental data and numerical results． The results showed that fluid calculation model of the peridynamic differential operator established can effectively simulate the whole process of fluid motion．The trend and extreme value of the velocity distribution curve are in good agreement with the existing results，and the characteristics of the flow field can also be clearly captured． © 2024 Huazhong University of Science and Technology.
