Summary, in English
This chapter presents a brief review of studies on swirling and non-swirling impinging jets. Also, a numerical investigation of heat transfer from impinging swirling jets is described. Various turbulence models are used. Comparison with experimental data is provided. Generally, the V2f model was found to perform better than other models, but for small nozzle-to-plate distances, it was hard to maintain good or sufficient accuracy. The difference in performance, in terms of the Nusselt number distribution on the impingement wall, between swirling and non-swirling impinging jets was clearly identified. The magnitude of the swirling motion has great infl uence on the flow field and the formation of recirculating zones and accordingly the heat transfer process. Keywords: Swirling jet, heat transfer, CFD, turbulence modeling
