WebApr 3, 2024 · The critical Reynolds number is the Reynolds number at which a laminar flow is expected to change into a turbulent flow! When a fluid flows over a flat plate, a turbulent flow is to be expected if the Reynolds numbers are greater than 100,000. In stirred vessels, the critical Reynolds numbers are around 10,000. WebThis study focuses on the experimental measurements of the heat transfer coefficient over a flat plate with a 30° leading edge. Under forced convection by a hot/cold air and flow over a cooled/heated flat plate, the thermal boundary layer and its thickness are quantitatively visualized and measured using a Mach-Zehnder interferometer. In addition, the variation …
