Effects of Surface Roughness on Windage Loss and Flow Characteristics in Shaft-Type Gap with Critical CO<sub>2</sub>

To investigate the effects of surface roughness on windage loss and flow characteristics in a shaft-type gap, the skin friction coefficient (<i>C</i><sub>f</sub>) and flow versus Reynolds number (<i>Re</i>) at different surface roughness (<i>Ra</i>) an...
