- 論文の詳細を見る
When a fluid enters a circular pipe with a rounded entrance from a large reservoir, the fully-developed velocity distribution can be attained only through the entrance region. Many non-Newtonian fluids have some elastic effects and the flow behavior in the entrance region is supposed to be affected by the elasticity of the fluid. In this report authors calculated the inlet length and the pressure loss of the viscoelastic fluid in the entrance region basing on the Weissenberg assumption and the momentum balance. As a result, the inlet length and the Hagenbach correction for the viscoelastic fluid flow are derived as functions of the rheological constant n and the dimensionless numbers R_6 and N_6.
