Specifically, we are trying to model water vapor aerosols (suspended water vapor molecules) in Nitrogen gas (primary fluid) in a cylindrical container with the following boundary conditions: the top surface is at a temperature T_low, the bottom surface is at a temperature T_high and the curved surface is at a temperature between T_low and T_high. These conditions are set for the initiation of Rayleigh-Bernard convection in the cylinder and to know the conditions that promote the formation, the size distribution, the residence time, and the dissipation rate of the particles.

You may want to look into these tutorial examples. FYI, selection of the modelling approach depends on the volume fraction of the secondary phase. Ideally, DPM is preferred when the VF of secondary phase is less than 10-12%. Otherwise, Eulerian approach is better.
DPM: Chapter 16: Effusion Cooling simulation in a 3D model Combustor (ansys.com)
DPM: Chapter 18: Modeling Evaporating Liquid Spray (ansys.com)
Eulerian approach: Chapter 21: Using the Eulerian Multiphase Model (ansys.com)

However, these tutorials are just for the reference as it won't cater your exact requirements. But I hope this helps!
