Coating in a Conventional Pan Coater

1 Model Assumptions The numerical model for coating was developed based on the following assumptions  

Physical properties such as Young s modulus and density were kept constant during the simulation. 

As very small amount of coating solution was introduced into the bed that dried immediately, the DEM model developed simply deals with a dry granular bed. Instead, the particles were color-coded based on their residence time under the spray zone for visual purposes. 

DEM simulations were performed using 40,000 particles (corresponding to 21% fill fraction) where the spray duration was 1 s and the time difference between the 

D is the diameter of the resultant progeny particle, is fracture toughness of material, (Pa m° ), is propagation velocity (m/s) of longitudinal elastic waves in the material, 5 is the induced strain rate. The strain rate in the sample is defined as the difference in particle velocity at the point of impact and at the opposite end of the sample.
