Investigation of thermofluid processes in the interfacial region

在流体-流体和流体-固体界面上的热传递速率对于许多环境和工程应用是至关重要的。建议的研究的目的是调查的基本流动和热过程的影响/控制的界面传热。它将集中在空气-水和固体-流体界面的调查。在空气-水界面处，空气和水之间的物理相互作用涉及许多复杂的现象，这些现象发生在空气和水的界面附近。由于流动的复杂性和具有挑战性的测量在波动界面附近的性质，跨空气-水界面的基本传输过程知之甚少。流体与固体壁面之间的热交换是各种能量系统中的基本传热过程。由于近壁区流场和热场的强烈相互作用，该区域的流动性质相当复杂且尚未得到很好的理解，因此，换热装置的设计和优化在很大程度上依赖于经验关系和体积特性。

The rate at which heat transfers across fluid-fluid and fluid-solid interfaces is critically important to many environmental and engineering applications. The proposed research is aimed at investigating the fundamental flow and thermal processes that influence/control the interfacial heat transfer. It will focus on the investigations at both air-water and solid-fluid interfaces. At the air-water interface, the physical interaction between air and water involves a number of complex phenomena, occurring on both air and water sides in the close vicinity of their interface. Due to the complexity of the flow and challenging nature of measurements in the vicinity of the fluctuating interface, the fundamental transport processes across the air-water interface are poorly understood. The heat exchange between a fluid and a solid wall is the fundamental heat transfer process in a wide variety of energy systems. Due to the strong interaction of flow and thermal fields in the near-wall region, the nature of flow in this region is quite complex and not well understood and thus, designing and optimization of heat exchanging devices is heavily relied on empirical relations and bulk characteristics.
