Web1 day ago · Non-auditory physiological effects or injuries that theoretically might occur in marine mammals exposed to high level underwater sound or as a secondary effect of extreme behavioral reactions ( e.g., change in dive profile as a result of an avoidance reaction) caused by exposure to sound include neurological effects, bubble formation, … WebFlow regime maps of ( a) LL-Rhombus and ( b) LL-Triangle, with deionized water as liquid phase. Bubble flow can also be less predominant in the LL-Triangle than in the LL-Rhombus since the flat wall of the triangular obstacle impinges on incoming flow and abruptly redirects it toward the curved sides of the mixer [ 17 ].
