Outline of Final Research Achievements

New formulation and development of program code based on the new formulation enable the numerical simulation for Non-Newtonian fluid such as fresh concrete and avalanche. The formulation was extended to handle with a Non-Newtonian fluid such as Bingham, shear-thinning and shear-thickening fluid and sand that moves with fluidity. Furthermore, the modification of discretization improved convergence of iterative computation for solving linear equations. Moreover, slump test was conducted, and the test result was compared with the numerical result to check the validity of this study.
