Other experiments made in 2004 with a wall jet along a circular wall show that Coandă effect does not occur in a laminar flow, and the critical ⁠ h / r ⁠ ratios for small Reynolds numbers are much smaller than those for turbulent flow. down to ⁠ h / r ⁠ = 0.14 with a Reynolds number of 500, and ⁠ h / r ⁠ = 0.05 for a Reynolds number of 100.
