You'd need to resolve the pressure pulses so you'd need a very fine mesh and tiny time step as you suggested. 

There are force report macros for DPM particles via a UDF. There are also DPM scalars. Do you need to model the pulses or can you use any of the acoustics options from Fluent and map that value onto the particle? 

Note, as this isn't part of the core code I'm very limited in what advice I can give. DPM scalars are covered in the UDF manual, and the Fluent acoustics is in the User's Guide. You may also find material in the Fluent Help system (tutorials and examples) and in Learning (Fluids - left menu here).Â
