This Engage grant is designed to address a unique and challenging design issue for Hatch related to the development of a new concentrate burner lance. Presently, advanced simulation tools, such as computational fluid dynamics (CFD) are widely employed to design various technologies; however, there is still a need for experimentation, and consultation with outside experts when designing certain components. The present proposal focuses on specially design supersonic nozzles to achieve high momentum ratios within the dispersion air of a concentrate burner lance. The project will focus on the characterization of current Hatch nozzle designs, and develop recommendations that will help Hatch complete the design of supersonic nozzles for the concentrate burner lance. For this purpose, particle image velocimetry measurements of the flow field will be performed for a range of nozzle design. This will assess the performance of the nozzles and quantify the effect of the thin boundary layers found in the small converging/diverging channels of the nozzles.

这项参与赠款旨在解决 Hatch 与开发新型精矿燃烧器喷枪相关的独特且具有挑战性的设计问题。目前，先进的仿真工具，例如计算流体动力学（CFD）被广泛应用于设计各种技术；然而，在设计某些组件时仍然需要进行实验并咨询外部专家。本提案的重点是专门设计的超音速喷嘴，以在精矿燃烧器喷枪的分散空气中实现高动量比。该项目将重点关注当前 Hatch 喷嘴设计的特性，并提出建议，帮助 Hatch 完成精矿燃烧器喷枪的超音速喷嘴设计。为此，将对一系列喷嘴设计进行流场的粒子图像测速测量。这将评估喷嘴的性能并量化喷嘴的小会聚/发散通道中发现的薄边界层的影响。
