Unformatted text preview: ENU 4133 Duct Flows Part 1 February 24, 2010 Duct Flows Coverage I Reynolds number regimes (Section 6.1) I Internal viscous flows & development length (Section 6.2) I Friction factors (Section 6.3 + notes) I Solution for laminar round tube flow (Section 6.4) I Friction factors in turbulent flows (Section 6.6) equations, roughness, Moody chart I Solving duct flow problems (Section 6.7 + examples) I Non-circular ducts (Section 6.8) I Minor losses (form losses) (Section 6.9 + notes) Section 6.5 covered later. Section 6.10 not explicitly covered. Sections 6.11 and 6.12 not covered. Reynolds Number Regimes (6.1) Laminar-turbulent transitions depend most strongly on Reynolds number: Re = VL (1) For internal flows, the velocity scale used is the average velocity . In round tube/pipe flow, the length scale is the diameter: Re round tube = V ave D = mD A = 4 m D (2) In round pipes, for a Reynolds number below 2100 (or 2000 or 2300), laminar flow prevails and the simple N-S solution from...
