Oblique Turbulent Jets in a Crossflow
Publisher: American Society of Civil Engineers
Abstract: A simple description of oblique turbulent jets in a uniform cross‐flow is achieved by following the motion of the jet in an oblique coordinate system, which moves with the crossflow. In the moving coordinate system, the ...
Confinement and Bed‐Friction Effects in Shallow Turbulent Mixing Layers
Publisher: American Society of Civil Engineers
Abstract: The transverse development of the turbulent mixing layers in an open channel flow of shallow water depth was investigated experimentally to study the confinement and bed‐friction effects. Mean and r.m.s. velocity profiles ...
Roll Waves in Mudflow Modeled as Herschel–Bulkley Fluids
Publisher: American Society of Civil Engineers
Abstract: We develop a multilayer model to study roll waves in mudflow of Herschel–Bulkley fluids initiated by periodic and localized disturbance. Simulations are conducted of the temporal development of periodic roll waves and ...
Experimental Study of Turbulent Concentration Flow Field in the Wake of a Bluff Body
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments were conducted to determine the turbulent concentration field in the wake of a normal flat plate. Dye was introduced behind the plate as the tracer. The measurement of the dye ...
Entrainment by Buoyant Jet between Confined Walls
Publisher: American Society of Civil Engineers
Abstract: Quasi‐two‐dimensional turbulence was investigated experimentally in an apparatus consisting of two closely spaced vertical parallel walls. A jet of salt water was injected downward between the walls. Entrainment of fluid ...
General Integral Formulation of Turbulent Buoyant Jets in Cross-Flow
Publisher: American Society of Civil Engineers
Abstract: The turbulent buoyant jet in a nonuniform cross-flow is formulated using a general integral method. The integral equations for the turbulent motion through the jet cross section are derived for a fixed control volume and ...
Shallow Turbulent Flow Simulation Using Two-Length-Scale Model
Publisher: American Society of Civil Engineers
Abstract: Numerical simulations of the planar starting jets were conducted using a two-length-scale turbulence model and a hydraulic code to study the effect of friction on 2D turbulence in shallow open-channel flow. The simulation ...
