2320 マッハツエンダー干渉計を用いたスリットを通る液体の特性に関する研究(S42-4 複雑流体の流動現象(4),S42 複雑流体の流動現象)  [in Japanese] 2320 A Study on the Liquid Property through a Slot by Using Mach-Zehnder Interferometer  [in Japanese]

It has been reported that even water known as Newtonian fluid shows a peculiar behavior in flows through a fine gap or pores [1]. This peculiar behavior is not made clear but should be investigated from many aspects not only for academic field but also for industries. In this study, we make so-called Newtonian fluids to flow through a two-dimensional slot and examine it by the rheo-optical technique: Mach-Zehnder interferometer is used and interference fringes are observed around the slot gap by record with a digital video camera. Ion Exchange Water, Silicone oil were used as test fluids. As a result, we obtained peculiar phenomenon in interference fringes which can not be explained by temperature change.
