About This Lesson

This study investigates bubble dynamics in a 2D boiling chamber using CFD analysis in ANSYS Fluent.
The 2D geometry was created in ANSYS Design Modeler and meshed using ANSYS Meshing, resulting in a structured mesh.
The simulation utilizes the Volume of Fluid (VOF) multiphase model coupled with an evaporation-condensation model for phase change.
A User-Defined Function (UDF) initializes a sinusoidal air layer at the chamber bottom.
The transient simulation examines bubble formation, growth, rise, and detachment over multiple time steps, visualized through volume fraction contours.
