Effectiveness Ntu: Parallel-flow
Heat exchanger effectiveness (ε) vs. number of transfer units (NTU) and capacity ratio (Cr = Cmin/Cmax) for seven flow configurations: parallel-flow, counterflow, shell-and-tube 1-pass, shell-and-tube 2-pass, crossflow both unmixed, crossflow Cmin mixed, crossflow Cmax mixed. Data digitized from Incropera Figures 11.10-11.15.
| hx configuration | sk | capacity ratio (dimensionless) | effectiveness (dimensionless) | ntu (dimensionless) |
