RISDissolution of Direct Ocean Carbon Sequestration Plumes Using an Integral Model Approach
Publisher: American Society of Civil Engineers
Abstract: We present the results of a double-plume integral model for a positively buoyant multiphase plume of liquid carbon dioxide injected at mid-depths
Liquid Volume Fluxes in Stratified Multiphase Plumes
Publisher: American Society of Civil Engineers
Abstract: This paper presents an optimization scheme to estimate the internal entrained fluid fluxes for multiphase plumes in stratification from indirect experimental measurements and applies the results to field-scale plumes. ...
Role of Slip Velocity in the Behavior of Stratified Multiphase Plumes
Publisher: American Society of Civil Engineers
Abstract: This paper presents direct measurements of multiphase plumes in stratification and correlates characteristic plume properties with the nondimensional slip velocity
Storm Identification and Tracking Algorithm for Modeling of Rainfall Fields Using 1-h NEXRAD Rainfall Data in Texas
Publisher: American Society of Civil Engineers
Abstract: A method to identify and track rainfall structures using
Hourly Disaggregation of Daily Rainfall in Texas Using Measured Hourly Precipitation at Other Locations
Publisher: American Society of Civil Engineers
Abstract: A method to disaggregate daily rainfall into hourly precipitation is evaluated across Texas. Based on measured precipitation data, the method generates disaggregated hourly hyetographs that match measured daily totals by ...
Experiments on Mass Exchange between Groin Fields and Main Stream in Rivers
Publisher: American Society of Civil Engineers
Abstract: Laboratory experiments are presented that model the exchange processes between a river and dead-water zones created by groin fields. The measurement methods include particle image velocimetry (PIV) at the water surface to ...
Double-Plume Integral Models for Near-Field Mixing in Multiphase Plumes
Publisher: American Society of Civil Engineers
Abstract: We present a generalized integral model for multiphase plumes in stratified ambient conditions based on the double-plume approach, where the plume is composed of a rising, multiphase core plume surrounded by a counterflowing ...
Measurement of Behavioral Properties of Entrained Ambient Water in a Stratified Bubble Plume
Publisher: American Society of Civil Engineers
Abstract: Flow properties of a bubble plume in density-stratified conditions are studied using planar laser-induced fluorescence (PLIF) flow visualization. Entrained ambient fluid is identified by applying an image intensity threshold ...
Particle Image Velocimetry Measurements of the Mean Flow Characteristics in a Bubble Plume
Publisher: American Society of Civil Engineers
Abstract: A direct measurement method for the velocity field in multiphase flows using the particle image velocimetry (PIV) and particle tracking velocimetry (PTV) methods is developed to study the flow characteristics of an unbounded ...
Concentration-Based Decomposition of the Flow around a Confined Cylinder in a UV Disinfection Reactor
Publisher: American Society of Civil Engineers
Abstract: The proper orthogonal decomposition (POD) is applied to spatial concentration data, obtained using laser-induced fluorescence (LIF), for the flow around a confined circular cylinder (R=4,900) and compared with their ...
