The rate at which heat transfers across fluid-solid interfaces is critically important to many engineering applications. Several new areas in engineering are emerging where better heat transfer rate is of utmost importance and crucial for their practical/commercial implementation. However, the efforts to advance their thermal performance are hampered by the lack of understanding of the fundamental thermofluid processes particularly in the interfacial regions. The objectives of the proposed research program are to investigate thermofluid processes in the interfacial/near-interfacial region and identify and understand the physical mechanisms that influence the heat transport process. In the proposed research program, the specific focus during the next grant period will be on the following three broadly interconnected key areas, 1. Near-interfacial thermofluid processes at low Reynolds numbers 2. Heat transfer process in nanofluids 3. Heat transfer processes in phase-change materials during solid-liquid phase transition The outcomes of the above three projects have significant long-term impact from energy efficiency and sustainability perspectives. The results from this research program will lead to (i) the improved efficiency of conventional thermal energy systems resulting in lower fuel consumption, and (ii) improved design of solar thermal and thermal energy storage systems to make solar thermal a reliable and clean alternative to a fossil fuel-based thermal energy systems.

在许多工程应用中，流体-固体界面的热传递速率是至关重要的。工程领域正在出现几个新领域，其中更好的传热率至关重要，并且对其实际/商业实施至关重要。然而，努力提高其热性能的阻碍缺乏了解的基本热流体过程，特别是在界面区域。 拟议的研究计划的目标是调查在界面/近界面区域的热流体过程，并确定和了解影响热传输过程的物理机制。 在拟议的研究计划中，下一个资助期的具体重点将放在以下三个广泛相互关联的关键领域， 1.低雷诺数下的近界面热流体过程 2.纳米流体的传热过程 3.相变材料固液相变过程中的传热过程 上述三个项目的成果从能源效率和可持续性的角度具有重大的长期影响。这项研究计划的结果将导致（i）提高传统热能系统的效率，从而降低燃料消耗，以及（ii）改进太阳能和热能储存系统的设计，使太阳能成为化石燃料热能系统的可靠和清洁的替代品。
