چكيده فارسي :
In this study, three-dimensional flow and heat transfer
in a spiral microchannel with rectangular cross
section have been investigated numerically. The noslip
condition and constant temperature on the walls
have been assumed. The effects of secondary flows
and flow reversal on heat transfer have been
investigated. Also the effects of Reynolds and
Richardson numbers on Nusselt number and friction
factor have been studied. Results show that, increasing
the Reynolds number increases the friction factor and
Nusselt number. Also increasing the buoyancy force along
the channel strengthens the reverse flows which lead to
increasing of friction factor and decreasing of Nu number.
