Mixing of the Immiscible Liquids in the Entrance Region of a T-Type Chamber Using Laser Induced Fluorescence (LIF) Method

Salman Movahedirad; Ali Akbar Sarbanha; Fahimeh Sobhanian

Volume 13, Issue 3 , July 2016, Pages 32-42

  A Laser Induced Fluorescence technique (LIF) has been used to study the mixing behavior of two emerging streams in a T-Type mixing chamber. A mixing index on the basis of digital image light intensities is calculated. It has been shown that averaging over more than 800 images leads to a stable mixing ...  Read More
