Turbulent hydraulic penetration from turbulent pipe flow into stagnant columns
Abstract
An experimental investigation was conducted on the depth of mixing of water from turbulent pipe flow into a vertically oriented pipe deadleg or stagnant column. The depth of turbulent penetration or mixing length (ML) was correlated as a function of the piping system Reynolds number (Re) and kinematic viscosity. The dimensionless mixing length (ML) is defined as the depth of hydraulic mixing divided by the inside diameter of the dead-leg. Water was pumped at flow rates between 40 l/min and 750 l/min through smooth tubing sections with inside diameters between 22 mm and 73 mm. Isothermal experimental runs were performed at water temperatures between 30 C and 80 C.
