Building A Wind Tunnel To Produce Shear Flow

Summer Undergraduate Research Fellowship (SURF) student, Yuyang Fan, working with Research Scientist Daegyoum Kim and Professor Morteza Gharib, has built a wind tunnel that produces shear flow—flow in which wind speed changes with position or time.  The tunnel is six feet long, four feet wide, and four feet tall.  It is made from 100 coaster-sized computer fans that blow air at around nine meters per second.
