Post-taping with different law of cross section variation and different degree of roughness allows changing pacnps ---. Division of tepododes along the length of the channel worker and exploring the effect of the distribution of heat supply and the degree of roughness; the stability of the flow. The degree of roughness of the streamlined surface of the tapes is determined by the type of turbulence of the incised holes,
