The influence of the surface radiation on the flow instability was significantly higher.
- class="label">•
The circulation of the flow was enhanced by the radiation effect.
- class="label">•
The shear stress of the turbulent flow was facilitated by the surface radiation.
- class="label">•
The surface radiation was dominant to the radiative heat transfer.
