ASSESSMENT STUDY OF LONGITUDINAL RECTANGULAR PLATE INSERTS AS TUBESIDE HEAT-TRANSFER AUGMENTATIVE DEVICES

A number of longitudinal rectangular plate inserts used as tubeside heat transfer augmentative devices have been numerically investigated and assessed in the present study. The tube is of the axially uniform heat flux type with a peripherally constant wall temperature and an adiabatic rectangular plate insert. The flow is laminar, thermally developed and of steady state. The effects of the aspect ratio of the rectangular plate, the radius ratio of the circumscribed circle of the rectangular plate to the tube, and the eccentric installation on the net effect between heat transfer augmentation and pressure drop increase are determined.
