WebApr 10, 2024 · The initial Reynolds number of the configuration is defined using the minimal viscosity ν min = 1.5897 × 10 − 5 m 2 /s obtained for air at 300 K. In order to assist the investigation of the vortex-flame interaction, a chemical reference time is defined using the ignition delay time of a H 2 /O 2 mixture ( Y H 2 = 0.0556 , Y O 2 = 0.233 ) at ... WebThe Reynolds number is a dimensionless number that nicely summarizes the fluid flow characteristics. For internal flows, laminar flow corresponds to Reynolds number values of less than approximately 2300, where the limit may be different for external flows. In other words, a systems designer can be reasonably assured that fluid flow will be ...
