Steady Laminar Flow in the Inlet Region of Rectangular Ducts

抄録

A steady laminar flow of an incompressible Newtonian fluid in the inlet region of rectangular ducts is analyzed by the integral method. The main results obtained are as follows. (1) The axial pressure variation agrees better with experimental data than theoretical results by other methods. (2) The development of velocity profile agrees somewhat with experimental data. (3) The additional pressure drop and the inlet length can be predicted with satisfactory accuracy.
