Thus, ε*b/V^3 represents a dimensionless quantity where K is the minor loss coefficient (the drop in the pressure coefficient per baffle), b is the baffle spacing, and V is the average velocity flowing through the channel when the baffle spacing is b. To be able to compare energy dissipation rate for different flow properties and geometry, we should always non-dimensionalize εThroughout this research paper, dimensionless epsilon was used to compare flow with different geometric and flow properties to ensure accurate comparison.
