Abstract To investigate the diffusion mechanism of expansible polymer grouting material in fractured rock mass，a numerical approach for simulating variable density grout diffusion in two-dimensional fracture is developed based on computational fluid dynamics theory，modern fluid field calculation method and moving interface tracking technology. For this method，the numerical solution of the two-phase flow system of polymer and water is attained by using FVM for discreting its governing equations，adopting Youngs method to track the interface of the two phase fluid，and employing SIMPLE algorithm to iteratively solve discretised momentum equations，pressure and velocity correction equation. The validity of the proposed method is proved by the example of variable density fluid freely expanding in the two-dimensional rectangular slot. Then the algorithm is used for simulating the expansible grout?s diffusion in two-dimensional plate fissure，and the results show that the method can dynamically display the distribution characteristics of the flow field and the displacement effect between poymer and water，which can lay a foundation for further research on the expansible polymer grouting material’s diffusion mechanism in fractured rock mass.
