Lifting the Veil on Turbulent Convective Heat Transfer over Rough Surfaces

通过了解表面粗糙度对对流传热的影响，该项目旨在减少与发电和运输中使用的燃气和蒸汽涡轮机表面粗糙度相关的不必要的加热和能量损失。燃气轮机和蒸汽轮机长时间运行导致的表面粗糙度会显著增加其表面的加热，增加燃料消耗和温室气体排放，并降低运行寿命。改进将允许涡轮机在更高的进口温度下运行，这将提高效率，减少燃料使用，环境排放和维护成本。

By understanding the influence of surface roughness on convective heat transfer, this project intends to reduce the unwanted heating and energy losses associated with surface roughness in gas and steam turbines used in power generation and transportation. The surface roughness that results from extended operation of gas and steam turbines can significantly increase the heating of their surfaces, increasing fuel consumption and greenhouse gas emissions, and reducing operational life. Improvements would allow turbines to operate at higher inlet temperatures which will increase their efficiency and reduce fuel use, environmental emissions and maintenance costs.
