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

Mean Flow Structure and Local Scour around Single and Two-Column Bridge Piers [PDF]
علوم و مهندسی آبیاری, 2019 Bridges constructed across rivers are among the most important structures, especially during and after flood events. Bridge piers are exposed to some hazardous factors such as local and contraction scour hydrodynamics.

Spatial patterns of scour and fill in dryland sand bed streams [PDF]
, 2013 Reproduced with permission of the publisher. © 2006 American Geophysical UnionSpatial patterns of scour and fill in two dryland ephemeral stream channels with sandy bed material have been measured with dense arrays of scour chains. Although the depth and

The Anatomical Record, EarlyView.Abstract Domesticated European rabbits (Oryctolagus cuniculus) have long been chosen as laboratory model organisms. Despite this, there has been no definitive study of the vertebral musculature of wild rabbits. Relevant descriptions of well‐studied veterinary model mammals (such as dogs) are generally applicable, but not appropriate for a species ...
