A numerical study is performed to investigate thermal transport phenomena of the laminarizing flows in strongly heated circular tube, channel and concentric annulus. When the pipe is at rest, it is disclosed that laminarization takes place, the velocity gradient near the heated wall is attenuated and the turbulent kinetic energy diminishes over the whole cross section along the flow. The presence of pipe rotation induces an attenuation in the turbulent kinetic energy and the turbulent heat flux, resulting in the promotion of laminarization of a gas flow.  If the channel and the concentric annulus are simultaneously heated from both side-walls with high heat flux, the fluid flow is laminarized as well as the tube flow case.  However, the presence of inner core rotation in the annulus suppresses the substantial reductions in the velocity and turbulent kinetic energy in the laminarzing flow. On the contrary, when the two-dimensional channel and the annulus with a stationary inner tube are strongly heated from a one-side wall, the fluid flow can not be laminarized even for the heat flux level which courses the laminarizing flow in the tube.
