Slides for ME 115 Laboratory Wind Tunnel Design Proper shape of the inlet is important – several journal papers offer guidance. Flow straighteners (honeycomb) and screens used to straighten flow and provide minimal turbulence intensity. Test section should not be too far downstream from inlet – otherwise boundary layers will be large for slow flows. If used, orifice plate or venturi tube must be design per strict ASME standards.
