This project aims to investigate and develop a novel air flow enhancement concept, induced plume swirl, and its engineering approaches to boost the cooling capacity of natural draft cooling towers (NDCTs). These towers are widely used in thermal power plants due to their low operating costs. The project will explore why and how the artificial natural convective air swirls (vortices) significantly increase the updraft inside NDCTs and identify effective, low-energy cost swirl inducement methods to increase the efficiency of operation. A wide application of this technology will result in economic and environmental benefits, including increases in overall energy conversion efficiencies, cuts in operational costs in the order of billions, and reductions in carbon emissions in the thermal power sector.

该项目旨在研究和开发一种新颖的气流增强概念——诱导羽流涡流及其工程方法，以提高自然通风冷却塔（NDCT）的冷却能力。由于运行成本低，这些塔被广泛应用于火力发电厂。该项目将探讨人工自然对流空气涡流（涡流）为何以及如何显着增加 NDCT 内部的上升气流，并确定有效、低能耗的涡流诱导方法以提高运行效率。该技术的广泛应用将带来经济和环境效益，包括提高整体能源转换效率、降低数十亿美元的运营成本以及减少火电行业的碳排放。
