Finite-difference analysis for unsteady squeezing flow of a second grade fluid between circular plates
Non-Newtonian fluids Squeezing flow
2010/9/27
The unsteady two-dimensional flow of non-conducting, incompressible second grade fluid between two circular plates approaching or receding from each other symmetrically is studied. A similarity transf...
