Gas conditioning towers (GCTs) or cooling towers have broad industrial applicability, especially in the cement industry. Most cement factories deal with the same problems faced by other factories. However, the solutions to these problems are barely internationally published and have not received much attention, meaning a lot of time and money is spent on researching previous solutions. Iran is among the top ten cement manufacturing countries in the world. Therefore, many of these problems have occurred in Iranian cement factories. The purpose of this paper is to provide a review of studies in this field over the last couple of decades, with a particular focus on advances in Iran. The most important findings in the literature are summarised in order to suggest the best possible solutions for improving the performance and lifetime of GCTs and decreasing common problems such as dust build-up and wet bottom. Numerical methods for modelling different aspects of GCTs are reviewed. The results can be used to reduce water and energy consumption, air pollution and the repair and maintenance costs of cement factories.

水泥厂气体调节塔多相流计算研究综述

气体调节塔 (GCT) 或冷却塔具有广泛的工业适用性，特别是在水泥行业。大多数水泥厂都面临着与其他工厂相同的问题。然而，这些问题的解决方案几乎没有在国际上发表，也没有受到太多关注，这意味着大量的时间和金钱被花费在研究以前的解决方案上。伊朗是世界十大水泥生产国之一。因此，伊朗水泥厂出现了很多这样的问题。本文的目的是回顾过去几十年该领域的研究，特别关注伊朗的进展。对文献中最重要的发现进行了总结，以便提出最佳解决方案，以提高 GCT 的性能和使用寿命，并减少灰尘堆积和底部潮湿等常见问题。回顾了对 GCT 不同方面进行建模的数值方法。研究结果可用于减少水和能源消耗、空气污染以及水泥厂的维修和维护成本。
