Agricultural Drone Sprayer CFD Simulation

This CFD simulation training explores agricultural drone spraying using ANSYS Fluent’s Eulerian multiphase flow model. The focus is on simulating the interaction between air and spray droplets in a field environment.

Key aspects of this simulation include:

Eulerian Multiphase Model Setup: Configuring the Eulerian model for the air-droplet system. Air is defined as the primary continuous phase and spray droplets as the secondary dispersed phase.

Simulation Domain: Using a pre-defined domain representing a section of an agricultural field.

Spray Nozzle Configuration: Defining spray characteristics at nozzle outlets, including flow rates and droplet size distributions.

Boundary Conditions: Setting up appropriate boundary conditions for the simulation domain.

Turbulence Modeling: Configuring a suitable turbulence model for the air-droplet system.

Transient Simulation: Setting up time-dependent aspects to capture the spraying process dynamics.

Post-processing and Analysis: Examining spray dispersion patterns, droplet trajectories, and deposition rates.

This simulation provides insights into agricultural spraying dynamics using the Eulerian multiphase approach. Participants will gain skills in applying this model to simulate spray behavior in an open field environment, focusing on the interactions between air and spray droplets.
