This book was released on 1970 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Observations are presented which show that the stresses in a flow field of a very dilute polymer are not well enough described by the Navier-Stokes equations to accurately predict cavitation. The constitutive equation for the particular polymer and concentration used is needed. The second-order fluid form in which accelerations are relatively important appears capable of explaining observed cavitation suppression by changing the pressure field due to flow. Bubble dynamics in stationary dilute polymer solutions are also examined and found to be little different from those in water. (Author).
