Simulation of Mixing Eveness of Two - component Polyurethane Borehole Sealing Material by CFD Technique
Abstract：Polyurethane is one of the most widely used material in borehole sealing. The two - component polyurethane must be mixed first in the static mixer before pumping into the drill hole. There. is no doubt that the mixing quality of polyurethane is very important to the sealing quality of various drillings. A mixing effect evaluation of uneven degree and sample variance through the mathematical meth- ods was established. Based on the previous studies, this paper designed a kind of special static mixer for mixing polyurethane, and car- ried on the optimization of the static mixer＇s structure by investigating the mixing effect of polyurethane through Fluent numerical simula- tion software.
