Résumé

Experiments were conducted to investigate heat transfer characteristics of water flowing through trapezoidal silicon microchannels with a hydraulic diameter ranging from 62 to 169 µm. A numerical analysis was also carried out. The experimental results were compared with the numerical predictions and a significant difference was found probably due to surface roughness and lower Nusselt numbers. Based on a roughness-viscosity model established in the authors' previous work, a modified relation was proposed.
