TITLE : EVAPORATING PARTICLES IN A SPRAY DRYER

BY : D B Spalding
FOR : CFD in Food Engineering - St. Johns College Cambridge#
PHOENICS Version : PHOENICS-GENTRA

DETAILS :

• Two-Dimensional Steady flow
• Curvilinear(BFC) computational grid

NOTES :

• A central, downward-directed spray vaporises in a hot gas stream
• Example of Two-Phase flow phenonema
• PHOENICS add-on module, GENTRA, is used for particle tracking

Pictures are as follows :
