Formation of a Polymer Thin Wall Using the Level Set Method

Abstract

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.
