CFD Case Study

CFD Flow Analysis of Venturi Scrubber to a Process Equipment Manufacturer, USA

The Client
Process Equipment Manufacturer, USA

The Objective

To obtain droplet size distribution/ Sauter mean diameter of liquid droplets, entering from the top nozzle to the venturi.

The Solution

The droplet size distribution and Sauter mean diameter (D32) was calculated assuming suitable model for particle tracking, droplet breakup, coalescence and heat transfer. Using different mean diameter calculation approaches, the droplet diameter was calculated at given plane.

Technology/Software
ANSYS Fluent 14.5

Challenges

Engineering Solution

In order to accurately measure the droplet size distribution and mean droplet diameter, the simulation domain was first modeled through CAD tools. Finer mesh was applied near the nozzle injecting area to capture accurate physics.

Discrete Phase Model (DPM) was used for particle tracking and pressure swirl model was utilized for droplet injection. Maximum and minimum droplet diameters were measured using different measurement approaches.
