Randomized trial develops new correlations for friction factors and pressure drops in rectangular microchannels, suggesting improvements for microfluidic designs.
Key Points
To develop new correlations for the friction factor and pressure drop in laminar flows within rectangular microchannels using CFD modeling.
Conducted 222 simulations for 37 Reynolds numbers mainly in low Reynolds number regime.
Validated results against existing data for Reynolds numbers greater than 100.
Developed three new correlations for friction factor and pressure drop based on simulation data.
New correlation for fRe showed a mean deviation of 0.14% and a maximum deviation of 0.26%.
K(∞) correlation was developed with a mean deviation of 1.75% and a maximum deviation of 4.99%.
K(z) correlation for the developing region had a mean deviation of 0.80% and a maximum deviation of 5.93%.
