摘要

设计了一种新的测垢实验装置

研究了模拟硬水CaCO_3在加热表面的结垢机理.提出了沉积-自由移去的结垢机制

并用湍流猝发理论结合Hasson的离子扩散模型

导出了碳酸钙结垢速率的数学模型

模型预测速率同实验数据吻合较好.

Abstract

A new experimental device was designed for fouling measurement

and the mechanism of calcium carbonate scaling on a heated surface was thus studied by using simulated hard water . A deposition-free removal mechanism of scaling was proposed and a mathematical model based on turbulent burst theory was derived with the combination of Hassons ionic diffusion model and the rate of scaling predicted with the model agreed well with the experimental data .
