Thickness Measurement of Liquid Sheet Spay Before Breakup

This paper presents the thickness measurement of liquid sheet spray. Two types of liquid sheet spray were measured, i.e. the wall impingement spray and flat spray. The measurement was carried out by a light absorption method using He-Cd laser and diode laser. Figure 1 shows the experimental apparatu...

The reason for these phenomena can be attributed to the ligament formation in the liquid sheet as shown in the Fig. 4. In other words, the increasing trend represents the moment when the 4-points of dye traces accumulated into the ligament, while the decreasing trends indicates the moment when the dye traces were located in between two ligaments. Therefore, the change of liquid sheet thickness between two ligaments can be clarified by the laser tagging method, which is normally difficult to be achieved by using the light absorption method. 2015 Conference or Workshop Item PeerReviewed application/pdf en http://umpir.ump.edu.my/id/eprint/11229/1/Thickness%20Measurement%20of%20Liquid%20Sheet%20Spay%20before%20Breakup.pdf Nurrina, Rosli and Kenji, Amagai (2015) Thickness Measurement of Liquid Sheet Spay Before Breakup.
