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.

现代热流体系统的日益复杂性对增强的设计工具提出了越来越严格的要求，这反过来又要求更好地理解热流体系统中的流体流动和传热。 一个可行的和相对便宜的方法来改善现有的设计工具是通过先进的数值模型，可用于工业热流体系统中的流体流动和传热的数值模拟的发展。 因此，可以减少对耗时且昂贵的测试的需求。 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，以改善/优化热流体系统。本研究的目的是：*（1） 改进发电厂冷凝器的性能;***（2）优化热裂解工艺流化床的设计; ***（3）提高工业干燥器的效率;***（4）开发核反应堆控制系统，以提高其安全性和效率。* 拟议研究的意义在于，它将为高效工业热流体系统的设计提供改进的设计工具，并培养高素质的人才（5个博士学位）。3名硕士研究生），他们不仅要具备流体流动和传热数值模拟的一般知识，而且要具备将这些知识应用于各种工业应用的能力。
