Cooling towers are widely used to dissipate the low-grade heat of thermo-electric power plants, chemical and petrochemical process industries, and refrigeration and air conditioning plants. Wet cooling tower requirements in the U.S. are about 3 times larger than all domestic water consumption. During cold winter months, wet cooling tower also produce visible plumes of condensed steam above the tower which can pose threats to agriculture and the transportation industries (air and ground) due to reduced visibility and even ice formation on neighbouring roads. Increased regulations on water consumption and plume visibility, combined with the requirement to develop power plants in more arid conditions where a dependable source of make-up water is unavailable, as it is typically the case for solar thermal and geothermal energy applications, requires engineers to develop tools to design improved cooling tower technologies.

冷却塔广泛用于散发热电厂、化学和石化加工业、制冷和空调厂的低品位热量。美国的湿式冷却塔需求量大约是所有生活用水量的 3 倍。在寒冷的冬季，湿式冷却塔还会在塔上方产生可见的冷凝蒸汽羽流，由于能见度降低，甚至邻近道路上结冰，可能对农业和运输业（空中和地面）构成威胁。对水消耗和羽流能见度的规定不断增加，再加上在更干旱的条件下开发发电厂的要求，而在这些条件下，无法获得可靠的补充水源（太阳能热和地热能应用的典型情况），要求工程师开发工具来设计改进的冷却塔技术。
