These predictions are typically done using inlet (Kc) and exit (Ke) loss coefficients for parallel plate channels from the Kays and London book, Compact Heat Exchangers. However, the information presented in Compact Heat Exchangers assumes fully developed flow at the exit. Electronic heat sinks ...
While the loss coefficients for a power-law fluid are smaller than those for a Newtonian one, the reverse is true for a Bingham fluid. In the limiting case of a concentric annulus, the results are found to be in good agreement with those reported in the literature.doi:10.1080/...
We assume ω = 2κ and κ > 0 (other cases are similar but omitted for brevity). Applying the Lamperti transform (2) to (12) and co√nditioning via (11) yields, after extensive but routine calculations, a diffusion on (ln τ / w, ∞) with drift and diffusion coefficients α(y)...

A logarithmic model was used to correlate branch and main loss coefficients as functions of branch-to-common and main-to-common flow rate ratio, respectively, and pertinent geometry characteristics of the fitting. Uncertainty analysis was performed on the measured experimental data. Coefficient of ...
The orientation of the entrances affects passenger flow and station accessibility, as well as lighting and ventilation [19]. The size of the portal, or entrance and exit dimensions, directly impacts congestion levels and passenger throughput [20]. Navigational clarity is crucial in subway ...
