Formation of a Polymer Thin Wall Using the Level Set Method

Considering foam’s expansive characteristics and using programming language, the level set method was used to simulate the polymer injection process that forms a thin wall; the influencing factors of the wall formation were studied for injection pressure, expansion ratio, and gel time. The polymer injection–wall-formation process was verified using a modeling test, and its molding effect was proven using a field test. The results show that the polymer injection technique can quickly form a thin wall, and it is feasible to use the level set method to simulate the polymer injection filling process and display the grout interface more accurately.
