January 15, 2017Flow visualization describes the art of making visible what is invisible. Using flow visualization techniques, scientists like da Vinci, Reynolds, and Prandtl discovered some of the most fundamental concepts concerning wakes and boundary layers. The rapid evolution of affordable electro-optics and digital image processing during the last several decades has increased...
November 03, 2017Adiabatic air-water studies were completed in a transparent vertical serpentine loop with a 12.7-cm internal pipe diameter and six vertical upflow and downflow sections with straight lengths exceeding 6 m. Liquid holdup in the vertical runs tends to dominate the overall pressure drop. This study focuses on flow visualization and pressure...
