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增长的复杂性对增强的设计工具施加了越来越严格的要求，这反过来又需要更好地了解热流动系统中的流体流量和热传递。 改善退出设计工具的一种可行且相对廉价的方法是通过开发高级数值模型，这些模型可用于工业热流体系统中流体流量和热传递的数值模拟。 因此，可以减少对耗时和昂贵的测试的需求。 该建议涉及制定和验证数学和数值模型及其在行业中的应用，以改善/优化热流体系统。 这项拟议的研究的目标是： （1）提高电厂冷凝器的性能； （2）优化流化床的设计，以进行热裂工艺； （3）提高工业干燥机的效率；和 （4）开发用于核反应堆的控制系统以提高其安全性和效率。 拟议的研究的重要性是，它将为高效率工业热流动系统的设计提供改进的设计工具，并培训高素质的人员（5博士学位和3名硕士学生），他们不仅具有数值模拟的一般知识流体流量和传热，但也具有在各种工业应用中应用一般知识的能力。
