Experimental study of bubble plume with CFD benchmarking
Abstract
An experiment and simulations were performed to study the characteristics of a bubble plume in water. Important results including experimental data and simulations are summarized. In order to study the bubble plume characteristics, an experiment was designed and carried out. The experiment consisted of a bubble jet being injected into a tank of water at different flow conditions using different injector configurations. In addition to the experimental work, CFD simulations with ANSYS CFX 13.0 were performed. Selected flow conditions were simulated to benchmark the experimental data, and important settings for boundary conditions and simulation strategy were recommended. The CFD analysis focused on the prediction of the recirculation fluid velocity. According to the benchmark results, the CFD simulation can predict the recirculation fluid velocity with an accuracy of ±26%.
