  • ABSTRACT: This paper presents heat transfer enhancement in single-phase transitional flow by wire-coil insert with geometrical parameters rib height-to-diameter ratio e/D=0.063, and rib pitch-to-height ratio p/e =5.6 ÷12.2. The paper presents variation of friction factor and heat transfer coefficient in the ranges of Reynolds and Prandtl numbers as 1100
