User Defined Functions (UDF) - Part 3 - UDF for Multiphase Flow Models in ANSYS FluentUser defined functions (UDF) 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 conditions, material models as well as various physical and chemical transformations such as heat transfer, chemical reactions or phase change. UDFs 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.
Part 3 of webinar series will dive into UDFs for multiphase flows. Multiphase UDFs can be employed for multiple purposes including the customization of mixture or phase specific properties, inter-phase interaction models such as drag, heterogeneous reaction rate and constitutive relations, and particle fate determining terms in case of a population balance models.
In this webinar we will first cover multiphase UDF related basic concepts like domain and thread. That will be followed by building blocks such as multiphase looping macros along with examples demonstrating their use. Finally mind maps will be presented showing connections between commonly used multiphase UDF tools to enable user to quickly get started with writing multiphase UDFs.
