The relation between the nanofluids properties is determined by using a heater mounted on a cavity wall. The base fluid is considered as water. The present study is focused on forced convection heat transfer from square heater subject to inflow and outflow inside a square cavity. The behaviorial physics will be reported in connection with volume fraction, Reynolds number and nanomaterial properties. It is noted that the local heat transfer is increased for a particular Reynolds number when nanomaterial is introduced. Constant Nusselt number attributed by the wall vortex. It is also found that we get high Nusselt number when the heater wall is subject to combination of vortex and main stream fluid rather than heat transfer due to wall attached vortices. For the same Reynolds number, nano fluid results high Nusselt number.
