Abstract

Comparative evaluation of thermal efficiency of single pipes with drop-shaped, plane-oval and circular forms of section at transversal flowing around in interval of Reynolds numbers ReD=3000...30000 is performed. For an evaluation and comparison of efficiency of pipes the modified specific friction loss coefficient was used, which takes into account an increase or decrease of area of surface of the compared tubes. Advantages and disadvantages of compared pipes are shown
