Abstract
The non-uniform air distribution in the drying chamber causes the uneven
moisture content reduction of material. The solution for more air uniformity in this
study is tuning air blade angle, and the CFD simulation method in COMSOL
Multiphysics® is applied to reduce the time and cost of solving this. After the test
with several values of air blade angle (15, 30, 40, 45, 50, 60 degrees), the
appropriately found result is 60 degrees.
