## Chapter 6: Particle Transport Theory

Particle transport modeling is a type of multiphase model, where particulates are tracked through the flow in a Lagrangian way, rather than being modeled as an extra Eulerian phase. The full particulate phase is modeled by just a sample of individual particles. The tracking is carried out by forming a set of ordinary differential equations in time for each particle, consisting of equations for position, velocity, temperature, and masses of species. These equations are then integrated using a simple integration method to calculate the behavior of the particles as they traverse the flow domain.

This chapter describes:

- Lagrangian Tracking Implementation
- Momentum Transfer
- Heat and Mass Transfer
- Basic Erosion Models
- Spray Breakup Models
- Particle Collision Model
- Particle-Wall Interaction
- Quasi Static Wall Film Model

The following section describes the methodology used to track the particles.
