Abstract：To address the issues of empiricism，accuracy loss，and repeated calculation of interface heights caused by the piecewise approximation strategy in interface reconstruction and the volume of fluid equation solving using the circle-based interface reconstruction （CIR） algorithm， an integration circle-based interface reconstruction （ICIR） algorithm is proposed. This algorithm employs a series of procesing strategies to achieve volume fraction solutions based on integration，effectively avoiding empirical interface segmentation and repeated solving of interface heights in each segment. Test results indicate that in a static test involving the random reconstruction of 1 000 （20 circular interfaces，the ICIR algorithm improves reconstruction accuracy by 7.71% compared to the CIR algorithm，with an acceleration ratio of 6.78 for solving the interface equation. In the horizontal motion test of a simple vapor bubble and the complex time-reversed single-vortex test， the ICIR algorithm enhances accuracy by 3.96% and 13.09% ，respectively，while computational efficiency improves by 40.88% and 68.31% . Overall， the ICIR algorithm significantly boosts computational efficiency and enhances the accuracy of interface reconstruction.
