Investigation of combined effect of nanofluid and swirling jet on heat transfer

Investigation of combined effect of nanofluid and swirling jet on heat transfer

The present study is focused on the numerical investigation of heat transfer from a heated surface by using nanofluids and swirling jets. Effects of different Reynolds number and different inlet temperature on heat transfer and fluid flow were studied numerically. Al2O3- H2O nanofluid was used as a base coolant in all parameters. k-ω turbulent model of PHOENICS computational fluid dynamics code was used for numerical analysis. It is obtained that increasing Reynolds number from Re=12000 to 21000 causes an increase of 51.3% on average Nusselt Number. Increasing inlet temperature from Tinlet=5 ºC to 30 ºC has not a significant effect on average Nusselt number.
