Research Abstract

To develop a large-eddy simulation(LES) method for non-Newtonian fluid such as surfactant solution, we performed direct numerical simulations(DNS) of turbulent channel flow and investigated features of wall turbulence of non-Newtonian fluid. As a result, we found, due to a scale analysis from a viewpoint of instantaneous structures and turbulence statistics, that the turbulent structures of non-Newtonian fluid could be generally normalized with the local variable viscosity as well as the case of Newtonian fluid. We suggested a modified model for LES and validated the reliability for turbulent flow of surfactant solution.
