Analysis of velocity profile geometry of laminar flow in a digonal duct
Journal Title: Вентиляція, освітлення та теплогазопостачання - Year 2016, Vol 19, Issue
Abstract
A velocity profile of stabilized laminar flow in digonal duct is analysed. The influence of axes length ratio on the Darcy coefficient is determined. When the ratio decreases the profile takes the saddle-like shape near to the digon vertexes with velocity gradient decrease. So the tangential tensions decreases that cause lower values of the Darcy coefficient. But in this case the specific pressure loss by the length increase at constant section area and flow rate
