| dc.description.abstract | The effect of roughness on pressure drop and heat transfer
in circular tubes has been extensively studied in literature.
The pioneering work of Nikuradse (1933) established the sand
grain roughness as a major parameter in defining the friction
factor during laminar and turbulent flows. Recent studies
have indicated a transition to turbulent flows at Reynolds
number values much below 2300 during single-phase flow in
channels with small hydraulic diameters. In the present work,
a detailed experimental study is undertaken to investigate the
roughness effects in small diameter tubes. The roughness of
the inside tube surface is changed by etching it with an acid
solution. Two tubes of 1.032 mm and 0.62 mm inner diameter
are treated with acid solutions to provide three different
roughness values for each tube. The Reynolds number range
for the tests is 500-2600 for 1.062mm tube and 900-3000 for
0.62mm tube. | en_US |
