Abstract

Macroscopic flow behavior of wormlike micellar solution confined to a channel is analyzed with multiscale simulation that is composed of the fluid dynamics simulation describing the macroscopic flow behavior and the coarse-grained micellar dynamics simulation describing the microscopic states of micelles. To decrease the noise coming from the thermal fluctuation of the microscopic simulator, we have compared two different noise reduction techniques (ensemble averaging and time averaging). We have selected the ensemble averaging noise reduction technique that is rather suitable to utilize the high performance of parallel computers. Startup flow profile of wormlike micellar solution analyzed with the multiscale simulation has shown an elastic flow that is caused by a microscopic structure in a fluid element.
