- This paper reveals the fundamental physical mechanism of a new aerothermal management method. The findings can pave the way to improve turbine end-wall cooling design by the latest development of advanced manufacturing technique. The novel engineered surface structure concept provides an extra design space and flexibility in turbine end-wall cooling, as well as other applications in turbomachinery. The results and valuable suggestions on design optimization strategy proposed in this paper have been well received by the industrial partner (siemens). The team has also been approached by other international research groups soon after the Journal publication
