How to obtain the Mass Flow Rate on a surface/plane per Particle Diameter (bin) when using a Rosin-Rammler Size Distribution?

• FAQ

Rosin-Rammler expression is a convenient representation of the particle size distribution when using the Discrete Phase Model (DPM) in ANSYS Fluent. Some of the applications where Rosin-Rammler diameter distribution is employed include liquid spray modeling and dust filter simulations. In such cases, one of the quantities of interest is to obtain the particle mass flow rate per particle diameter bin. This data can then be used to assess the spray distribution or evaluate the separation efficiency of dust filters based on the particle sizes. Refer to the attachment for detailed discussion on how to obtain the mass flow rate v/s particle diameter distribution.
