要約

The experimental study of fluid dynamics and heat transfer in plane channels with different turbulators at Re below 2000 is presented.
The experimental study considered external as well as internal turbulators as a means of heat transfer augmentations. It included a supersonic jet of an ejector placed near by a channel, a flat grid of fins, corrugated and perforated nets and sets of staggered cylinders, placed in the middle of a plane channel. Turbulence parameters were measured. Turbulence intensity in the channel was up to 20%. Heat transfer similarity equations for all types of turbulators were compiled. Corrugated nets were most effective.
