The paper considers formation on the channel wall of a turbulent tornadolike vortex with increasing length of the longitudinally oriented groove tip deflected by the angle of 45o. Rearrangement of the separated flow structure in the groove inlet part is associated with formation of an increasing transverse extraordinary pressure drop and is accompanied by a drastic intensification of the swirling flow in the groove and of the vortex heat transfer. Keywords: separated flow, tornadolike vortex, narrow channel, longitudinal groove with deviated tip, intensification, heat transfer, numerical modeling.
