TITLE : TURBULENT MIXING IN AN 'S' SHAPED DUCT

BY : S Zhubrin - CHAM-MEI

DETAILS :

• The PREMIX (PREdiction of MIXing) program is used to simulate turbulent mixing of different gases in a curvilinear duct.

• Three streams enter at the bottom of the duct, each with a distinct temperature and NO2 concentration.

• An orifice plate is located at the apex of the first bend to assist mixing.
