Abstract
This report shows the fluid property and the velocity profile of carbon nanotube suspension (CNT). The CNT suspension is complex fluid. Complex fluid is defined as any fluid that does not follow the well-known Newton's law. In this study, two-dimensional velocity profiles of CNT suspension were measured between parallel plates and at the upstream region of the contraction. These results show that the velocity profiles in CNT suspension between parallel plates were in good agreement with Newtonian one. However, the results in CNT suspension at the upstream region of the contraction were not agreement with Newtonian one. This is because the elongational viscosities of CNT suspension effect at the upstream of the contraction.
