A COMPUTER ANALYSIS OF TURBULENT FLOW OF ACID IN THE PICKLING OF STEEL STRIPS

摘要

This paper presents computational results from a realistic three-dimensional computer model for the flow of acid in a pickling tank where acid is used to remove oxides scale on the steel strip. Special focus will be placed on the kinetic energy of the turbulent flow around the moving strip. The distribution of the turbulent kinetic energy, as an indication of the pickling rate, is analysed. Various processing conditions will be presented, including the effects of strip vibrations on the turbulent flow.
