Laminar Flow in Curved Pipes

Steady laminar flow in a curved pipe of circular cross section is investigated. It is assumed that the flow consists of a frictionless central core surrounded by a boundary layer. A formula for the friction factor of a curved pipe is derived, and the discharge coefficient for a 360-deg elbow flowmeter is discussed. Die stationare laminare Stromung in einem gekrummten Rohr von kreisformigem Querschnitt wird untersucht. Es wird angenommen, das man das Stromungsfeld eine reibungslose Kernstromung und eine wandnahe Grenzschicht aufteilen kann. Man erhalt eine Widerstandsformel fur das gekrummte Rohr. Auserdem wird die Durchfluszahl eines als Mengenmesinstrument verwendeten 360°-Krummers behandelt.
