DescriptionImpinging jets are a well known way of dissipating heat off surfaces due to their high heat transfer rates. This project aims to determine the enhancement effect of inducing a swirling flow into an impinging jet. four swirl generating inserts, each with different geometric aspects, are designed and placed in a contoured nozzle impinging jet to compare with a non-swirling jet. to characterise the change in heat transfer due to the inclusion of these inserts, infrared thermography is used along with hot-film sensor measurements and a range of flow rates and nozzle-to-surface heights. results found through these thermal measuring applications are compared against fluctuating heat transfer data and flow visualisation techniques to determine not only if there is a level of enhancement in the heat transfer but also what causes it.
