Numerical Studies of Two-phase Flows and Heat Transfer

现代热流体系统的日益复杂，对改进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了解热流体系统中的流体流动和热传递。改进现有设计工具的一种可行且相对廉价的方法是开发先进的数值模型，这些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，可以减少对耗时和昂贵的测试的需要。*本研究的目标是：*(1)改进电厂冷凝器的性能；*(2)优化热裂化过程的沸腾床设计；*(3)提高工业干燥机的效率；*(4)开发核反应堆的控制系统，以提高其安全性和效率。*这项研究的意义在于，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名博士生和3名硕士研究生)，他们不仅拥有流体流动和传热数值模拟的一般知识，而且有能力将一般知识应用于各种工业应用。

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.
