文摘

Pressure drop and heat transfer properties of triangular pipe were obtained. Phenomena of pressure drop and heat transfer reductions were clarified. Correlations between pressure drop ratio and heat transfer ratio were obtained. Correlation eq. between slush Re number and pipe friction factor was derived. Integrated pipe friction factor eq. for triangular and circular pipes was proposed.
