✦ Synopsis

A numerical study is presented for the heat transfer enhancement in a horizontal tube due to the insertion of an adiabatic plate. Special attention is placed on the effects of the eccentricity and tilted angle of the inserted plate on the heat transfer enhancement. The governing equations are first transformed into curvilinear coordinates, then discretized into the finite difference form through the finite-volume method. It is found that the greater the eccentricity, the smaller the pressure drop, and the worse the heat transfer effect. Also, the optimum position of the inserted plate is found to be at the center of the tube.
