Spray Painting Simulation using Ansys Fluent

Electrostatic Spray-Painting Analysis using Ansys Fluent

This workshop explains the case set up and solution procedure for analyzing the effect of electrostatic field on charged particle motion during Electrostatic Spray Painting using Ansys Fluent® fluid simulation software.

Learning Outcomes:

Following completion of this workshop, you will be able to:

• Understand how to setup the case and solve for analyzing the effect of Electrostatic Field on the Charged Particle motion using Ansys Fluent.
• Learn how to use the Potential model and obtain an electrostatic field between anode and cathodes.
• Understand how to use User Defined Function (UDF) to provide additional Body Force term in DPM.

Modeling Spray Painting with Evaporating Particles using Lagrangian Wall Film

Spray painting is a painting technique in which highly atomized paint particles are sprayed through air onto a surface. In this demo tutorial, spray painting is modeled with Lagrangian wall film approach. Atomized paint particles are injected by solid cone injection. Particles upon hitting a cylindrical surface form a film. Subsequently film is tracked on the surface coupled to the gas phase.

Learning Outcomes:

Following completion of this workshop, you will be able to:

• Use DPM model and setup injection for releasing particles.
• Set up the case for evaporating paint particles using Droplet DPM and Species Transport Model.
• Use particle tracks for visualizing the particles.

Modeling Spray Painting with Non-Evaporating Particles Using Lagrangian Wall Film

Spray painting is a painting technique in which highly atomized paint particles are sprayed through air onto a surface. In this demo case, spray painting is modeled with Lagrangian wall film approach. Atomized paint particles are injected by solid cone injection. Particles upon hitting a cylindrical surface form a film. Subsequently, the film is tracked on the surface coupled to the gas phase.

Learning Outcomes:

Following completion of this workshop, you will be able to:

• Use DPM model and setup injection for releasing particles.
• Set up the case for non-evaporating paint particles.
• Use particle tracks for visualizing the particles.
