Abstract

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.
