A low shear rate turbulent flow apparatus

Abstract

This paper describes some experiments on a turbulent flow viscometer consisting of a continuous pipe loop of transparent material mounted on a circular wheel. The wheel is partially filled with fluid and rotated at a constant speed. The results show that the apparatus gives sensible results and although only a limited range of Reynolds numbers is possible it can be used as a useful qualitative apparatus to test dilute fluids which have abnormal turbulent flow properties.
