TURBULENCE IN THE WALL PART OF A FLOW FOR VARIABLE 
THERMOPHYSICAL PROPERTIES OF THE FLUID

A theoretical method of finding the thickness of the wall 
layer when an artificial turbulizer is installed in the flow is proposed. 
The site of location of the turbulizer is determined for maximum intensification 
of heat exchange in the case of constant and variable thermophysical 
properties of the fluid. It is established that incorrect selection 
of the site improves the heat transfer only slightly due to the growth 
in hydraulic resistance.
