Journal of Applied Mechanics and Technical Physics Aims and scope

Abstract

Results are presented from an experimental study of the effect of injection and temperature nonuniformity on the coefficient of friction in the entry region of a tube. A method is proposed whereby the kinematic flow characteristics can be used to determine the coefficient of friction directly from experimental data. This method has been applied to the data of various authors. The results of experiments carried out over a wide range of conditions are reported.
