Original abstract

The hot steel plate with embedded thermocouple was sprayed by nanofluid Al/water. The inverse heat transfer technique was then applied to convert the measured temperatures into the heat transfer coefficient (HTC) for different nanoparticle fractions and different nanofluid flow rates. The results showed 20% decrease of HTC with nanoparticle fraction increasing from 0 to 16.45%. The HTC corelations with the nanoparticle fraction and nanofluid flow rate were also reported.

Czech abstract

Ocelová deska se zabudovaným termočlánkem byla chlazena ostřikem nanokapalinou Al/voda. Z naměřených teplot byl pomocí inverzní úlohy vedení tepla určen součinitel přestupu tepla (HTC) pro různé průtoky nanokapaliny a různé koncentrace nanočástic. Ukázalo se, že HTC pro koncentrace nanočástic 0 – 16.45% poklesne přibližně o 20%. V článku jsou dále diskutovány závislosti HTC na koncentraci nanočástic v nanokapalině a jejím průtoku tryskou.
