Simulation of heat transfer from swirling impinging jets

På svenska

Author

Summary, in English

This paper presents a numerical investigation of heat transfer from impinging swirling jets. 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 accuracy. The difference in performance, in terms of the Nusselt number distribution on the impingment wall, between swirling and non-swirling impinging jets was clearly identified. The magnitude of the swirling motion has great influence on the flow field and the formation of recirculating zones and accordingly the heat transfer process. Copyright
