VELOCITY AND TEMPERATURE DISTRIBUTIONS AT THE TURBULENT SEPARATED FLOW BEHIND BACKSTEP IN THE CHANNEL
Abstract
This paper presents results of the detailed
statistical characteristics investigation of the velocity
and temperature fields for constant heat flux on the
wall at the separated flow zone behind backstep. These
results were obtained with high space accuracy and
can be used for an approbation of the turbulent heat
transfer models in the separated flows near a wall.
Obtained data shows, that maximum coordinates of the various values profiles is almost coincide. Fluctuating characteristics distributions discovered the existence of a zone with higher level of turbulence. This zone take place in main recirculating vortex field.
The peculiarities of the local heat transfer were analysed.
