Friction and heat transfer in drag-reducing surfactant solution flow through curved pipes and elbows
K. Gasljevic,E.F. Matthys +1 more
TL;DR: In this article, a study of drag-reducing flow in curved pipes was conducted and it was shown that if we use a modified definition of drag reduction that includes only the turbulence effects, we observe indeed the same level of reduction in both coiled and straight pipes.

Water-to-water heat transfer in tube¿tube heat exchanger: Experimental and analytical study
TL;DR: In this article, the authors present an experimental study on various layouts of TTHE for water-to-water heat transfer, and the experimental results also indicate that there is a definite optimum for a number of bends in serpentine layout TTHE.

Heat transfer in a straight tube situated downstream of a bend
TL;DR: In this article, the axial variation of the local heat transfer coefficient in a straight tube situated downstream of a bend is measured by a mass transfer technique for parametric values of the Reynolds number (5000-85000), bend turn angle (0, 30, 60, and 90°), and flow condition at the bend inlet.
