CFD Case Study

Predict Flow Behavior of Spray Nozzle Design for the Gas Scrubbing Application

The Client
Environmental Systems, USA

The Objective

The goal of CFD simulations is to ascertain the spray angle of the nozzle and verify that it meets a required range of 15º-20º based on the process conditions

The Solution

Based on the CFD results, the nozzle exit effective angle (measured from the center-point) is 20.28 degrees. By the time the flow covers 189.438” axially to reach the venture throat; it would have spread across 67.761

Technology/Software
ANSYS Fluent 14
CFD helps to Predict the Flow Behavior of Spray Nozzle Design for the Gas Scrubbing Application

Challenges

Engineering Solution

Hi-Tech CAE utilized ANSYS Fluent v14.0 software to perform multiphase flow analysis for the CFD project. The model design and geometry was conducted utilizing ANSYS DesignModeler software. A detailed three dimensional CFD model was constructed for the prediction of flow behavior of spray nozzle design. The analysis was performed to determine the droplet diameter size and distribution for the newly designed spray nozzle. The objective was to find out the Sauter mean diameter (S32) of the spray nozzle. Based on the CFD results, the nozzle exit effective angle (measured from the center-point) was 20.28 degrees. By the time the flow covered 189.438” axially to reach the venture throat; it would have spread across 67.761.
