Cavitation in Non-Newtonian Fluids

Cavitation-Enhanced Mechanical Effects and Applications

“…Based on a Thus far, it has been assumed that cavitation bubbles occur in Newtonian fluid. As non-Newtonian fluids are more prevalent in biomedicine and bioengineering application, in his book Brujan (2011) systemically discussed cavitation and bubble dynamics in non-Newtonian fluids from the standpoint of non-Newtonian fluid mechanics, physics, chemical engineering, and biomedical engineering. Figure 5.21 shows a series of high-speed photographic records of bubble motion in water, a 0.5 % carboxymethylcellulose (CMC) solution with a weak elastic component, and a 0.5 % polyacrylamide (PAM) solution with a strong elastic component for the case where γ = 3.17 (Brujan et al 1996).…”

“…In addition to the properties of the liquid surrounding the bubble and the distance to the boundary, the elastic properties of the nearby boundary material strongly influence bubble dynamics (Brujan 2011). In biomedical applications of cavitation, most boundaries near bubbles are non-rigid, e.g., vessel walls, cell membranes, and tissue surfaces.…”

“…According to Ref. [15], the velocity vector field is represented by u x 5_ e p x; u y 52_ e p x; u z 50:…”

Microfluidics control the ballistic energy of thermocavitation liquid jets for needle-free injections

“…When laser light is focused in a liquid with a sufficiently high absorption of the particular laser wavelength, a vapour bubble can be formed [1][2][3][4][5][6]. Depending on the confinement conditions this bubble can grow and expel the surrounding liquid through a nozzle creating a liquid jet.…”
