Many process applications involve the transport of solid particles, liquid droplets or gaseous bubbles by a continuous fluid. Especially if there is a range of sizes in the disperse phase, or if there is mass transfer causing the particles/drops/bubbles to change size, this type of flow can be best modeled in the ANSYS CFX software using the particle transport model.
In this model, the passage of a representative fraction of the particles (which generically here can mean also drops or bubbles) is tracked through the continuous fluid. This tracking progress not only calculates the position of each particle, but also its velocity, temperature and mass, as well as the effect that the particle has on the continuous fluid.
In addition to standard models of momentum and heat transfer, the ANSYS CFX software has an evaporation model for accurate modeling of drying processes; secondary break-up models for modeling sprays; erosion models to enable the effect of particles on walls; and a generic reaction model which enables combustion processes of pulverized fuels to be calculated.
