Deflection of Jets by Weak Crossflows
Publisher: American Society of Civil Engineers
Abstract: This paper presents a simple analytical method for the calculation of the trajectories of jets in weak crossflows. Assuming a general similarity of the jet, a simple convection relation with no experimental coefficients ...
Effect of Applying Different Distribution Shapes for Velocities and Pressure on Simulation of Curved Open Channels
Publisher: American Society of Civil Engineers
Abstract: Most of the computational models of curved open channel flows use the conventional depth averaged De St. Venant equations. De St. Venant equations assume uniform velocity and hydrostatic pressure distributions. They are ...
Predicting Flow in Curved Open Channels by Depth‐Averaged Method
Publisher: American Society of Civil Engineers
Abstract: A depth‐averaged model formulated in the Cartesian coordinate system is introduced for simulating the velocity distribution in curved open channels. The finite element method is used to simplify the geometry problems in ...
Physically Based Hydraulic Jump Model for Depth-Averaged Computations
Publisher: American Society of Civil Engineers
Abstract: Consideration of momentum conservation within a hydraulic jump leads to the conclusion that both the momentum correction due to the nonuniform mean velocity profile and the depth-averaged turbulent normal stress are important ...
Modeling Overfalls Using Vertically Averaged and Moment Equations
Publisher: American Society of Civil Engineers
Abstract: A new set of vertically averaged and moment equations, which assumes a linear longitudinal velocity distribution and quadratic vertical velocity and pressure distributions, is used for modeling flow in the vicinity of ...
Potential-Flow Solution to 2D Transition from Mild to Steep Slope
Publisher: American Society of Civil Engineers
Vertically Averaged and Moment Equations Model for Flow over Curved Beds
Publisher: American Society of Civil Engineers
Abstract: A new set of vertically averaged and moment equations, which assumes linear horizontal velocity distribution as well as quadratic vertical velocity and pressure distributions, along with a reduced set of vertically averaged ...
Influence of Water Drag and Headspace Air Pressure on Airflow in Sanitary Sewers
Publisher: American Society of Civil Engineers
Abstract: Odor complaints are widely reported due to hazardous gases being released from sewer systems. Mitigating and controlling the emission of these gases is the key to a better air environment. Existing airflow system models ...
Water Surface at Change of Channel Curvature
Publisher: American Society of Civil Engineers
Abstract: In the study of flow in curved open channels, it is observed that a gradual transition from a flat to a superelevated water surface occurs when the curvature of the channel is abruptly changed. The length of this transition ...
LDA Measurements in Open Channel
Publisher: American Society of Civil Engineers
Abstract: This paper presents mean velocity and some turbulence measurements for uniform subcritical flow in a smooth rectangular channel for three aspect ratios equal to 5.08, 7.83, and 12.3 obtained with a Laser Doppler Anemometer. ...
