User Defined Functions (UDF) - Part 2 - UDF for Discrete Phase Models in ANSYS Fluent

User defined functions (UDF’s) allow you to modify the behavior of ANSYS Fluent to satisfy your particular modeling needs. For example, these modifications may be used to impose desired initial and boundary, material models as well as various physical and chemical transformations such as heat transfer, chemical reactions or phase change. UDF’s are flexible and powerful, and allow you to use ANSYS Fluent as a framework to implement new models.

In this five part webinar series our aim is to present the fundamentals of developing UDFs. After a first webinar on the basic aspects of UDFs, we will deal with advanced topics such as UDFs for multiphase flow, Lagrangian Particle Tracking, reacting flow models and other advanced topics such as making your UDF's work in parallel.

In Part 2 of this webinar series, we will highlight the different macros available for DPM model and explain how to use them efficiently. Discrete Phase Model is used to simulate a variety of gas-liquid and gas-solid systems, IC engine, solid and liquid fuel combustion, sprays, scrubbers and more. DPM UDF allow you to modify many aspects of the particle trajectory and interaction with the continuous phase like mass transfer, drag, particle-wall behavior, injection logic, particle properties, particle forces, etc.
