The growing complexity of modern thermofluid systems has imposed increasingly stringent requirements on enhanced design tools, which, in turn, requires a better understanding of the fluid flow and heat transfer in the thermofluid system. A viable and relative inexpensive approach to improve the exiting design tools is through the development of advanced numerical models that can be used for numerical simulations of fluid flow and heat transfer in industrial thermofluid systems. Thus, the need for time-consuming and expensive testing can be reduced. This proposal deals with formulating and verifying mathematical and numerical models and their applications in industries to improve/optimize the thermofluid systems. The goals of this proposed research are: (1) to improve the performance of power plant condensers; (2) to optimize the designs of fluidized beds for thermal cracking process; (3) to increase the efficiency of industrial dryers; and (4) to develop control systems for nuclear reactors to improve their safety and efficiency. The significance of the proposed research is that it will provide improved design tools for designs of high efficiency industrial thermofluid systems, and train highly qualified personnel (5 Ph.D. and 3 master's students) who will not only have the general knowledge of numerical simulations of fluid flow and heat transfer, but also have the ability to apply the general knowledge in various industrial applications.

现代热流体系统日益复杂，对增强设计工具提出了越来越严格的要求，这反过来又需要更好地了解热流体系统中的流体流动和传热。 改进现有设计工具的一种可行且相对便宜的方法是开发先进的数值模型，该模型可用于工业热流体系统中流体流动和传热的数值模拟。 因此，可以减少对耗时且昂贵的测试的需要。 该提案涉及制定和验证数学和数值模型及其在工业中的应用，以改进/优化热流体系统。 这项研究的目标是： (1)提高电厂凝汽器的性能； (2)热裂化工艺流化床优化设计； (3)提高工业干燥机的效率；和 (4)开发核反应堆控制系统，提高其安全性和效率。 该研究的意义在于，它将为高效工业热流体系统的设计提供改进的设计工具，并培养不仅具备数值模拟一般知识的高素质人才（5名博士生和3名硕士生）流体流动和传热的知识，而且还能够将一般知识应用于各种工业应用。
