Calculation of Pressure Drop of Condensation on The Shell-side of ROD-baffle Condenser

折流杆冷凝器的突出优点是流动阻力小,因而受到越来越多的重视.思勤等论述了折流杆冷凝器的结构特点及冷凝传热的计算方法,本文进一步探讨冷凝压降的计算.

In this paper the pressure drop ot condensation on the shell-side of ROD-baffle condenser is analyzed. The simple expressions tor calculating pressure drop through the shell-side of the condenser were proposed. They were verified by an experiment, in which saturated vapor ot solvent naphtha condensed on the shell-side of ROD-baffle condenser, and by an industrial experiment on the consensation of naphtha-vapor on the top of a primary tower. It was proved that the method mentioned is reliable.
