Dam break wave of non-Newtonian thixotropic fluid


Description
Thixotropy is the characteristic of a fluid to form a gelled structure over time when it is not subjected to shearing, and to liquefy when agitated. Thixotropic fluids are commonly used in the construction industry e.g., liquid concrete and drilling fluids, and related applications include some forms of mud flows and debris flows. This video describes a basic experimental study of dam break wave with some thixotropic fluid (bentonite suspensions) down a 15 degree channel [1,2,3]. After a brief introduction, the video presents 4 tests. The last 3 tests illustrate the effects of the rest time on the fluid propagation down the slope. The work was conducted at the Laboratory of Materials and Structures in Civil Engineering LMSGC (France.).
