FEATURES OF FLOWING ROUND AND HEAT TRANSFER OF ONE-ROW OF CYLINDERS WITH SPIRAL GROOVES IN INTERACTION WITH A CROSS - FLOW OF AIR

The results of an experimental study of the average heat transfer, hydraulic resistance and vortex structure at the cross flow of a single-row of round cylinders with spiral grooves on the external surface are presented. The equations of similarity on the average heat transfer and hydraulic resistance were obtained
