CFD Modeling and Experimental Study of a Spray Dryer Performance

  • Maryam Sadripour , Amir Rahimi EMAIL logo and Mohammad Sadegh Hatamipour


The performance of a pilot-scale spray dryer is investigated experimentally and theoretically. The governing equations for flow field, heat and mass transfer, and particle trajectory are solved by applying computational fluid dynamics (CFD). The effects of inlet air temperature and initial particle diameter on the outlet humidity and particle residence time are examined. These parameters should be considered carefully in proper designing of spray dryers especially for the heat-sensitive products. The model is validated with an error of 5.5%.
