Influence of Wall Deformation Structure on the Liquid Film Flow Behavior Under Turbulent Conditions
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT To explore the influence of typical wall deformation structure in the scrubbing‐cooling tube on the liquid film, this paper studied the liquid film flow behavior on the riblet walls with representative riblet radii and compared them with the flat wall. Under different liquid film Reynolds numbers (Rel = 8.3 × 103 ~ 3.14 × 104), the liquid film

Single camera 3D planar Doppler velocity measurements using imaging fibre bundles [PDF]
, 2006 Two frequency planar Doppler Velocimetry (2ν-PDV) is a modification of the Planar Doppler Velocimetry (PDV) method that allows velocity measurements to be made, quickly and non intrusively, across a plane defined by a laser light sheet.
