- Specific surface area is a key parameter in particulate systems.
Purpose of the Study:
- To investigate the relationship between specific surface area and particle size distribution sharpness.
- To evaluate the performance of different distribution equations in describing particulate systems.
- To identify the most suitable equation for predicting specific surface area.
Main Methods:
- Simulated particulate systems were analyzed.
- Specific surface area was studied as a function of the sharpness parameter.
- The Gates-Gaudin-Schumann, Gaudin-Meloy, and Rosin-Rammler equations were employed.
Main Results:
- All tested equations showed statistical adherence.
- The Rosin-Rammler equation demonstrated particularly good performance.
- The best fit was observed when the Rosin-Rammler equation accurately described the particle size distribution.
