Spray CFD Simulation Training Package, 8 Practical Exercises: Advanced Level

• In this comprehensive study, three distinct cases were investigated to analyze the effectiveness of spray cooling approaches utilizing ANSYS Fluent software.
• The simulation setup began with the creation of detailed geometry using SpaceClaim, followed by the generation of a high-quality quadrilateral mesh in ANSYS Meshing.
• Three simulation cases were compared: baseline airflow only (Case 1), water injection with inert particles (Case 2), and water injection with  droplet interactions and phase change
• A two-way coupling approach was employed in the DPM configurations to capture the complete interaction between the discrete phase and the continuous flow field.
