The apparent viscosity (pseudoplastic viscosity) of mucilage of leucaena seed gum was calculated, based on flow curves, obtamed With multiple point viscometer. Attempts were made to correlate the various rheological properties, describIng the_ overall flow behaviOur of gum, with their concentrations. The relationship between N(exponential constant) and concentration was found to be a zero order...

The authors' study of the viscosities of various concentrations of sodium hyaluronate, chondroitin sulfate, and methylcellulose revealed that sodium hyaluronate and methylcellulose are pseudoplastic fluids in contrast to chondroitin sulfate, which is a Newtonian fluid. Pseudoplastic fluids are ideal for maintaining the anterior chamber, since they are more viscous at rest. Intermediate viscosit...

In the present work we explore an approximate solution of the Navier-Stokes equations for optical fiber coating in a pressure type die by withdrawal from a bath of two immiscible Oldroyd 8-conatant fluid under constant pressure gradient in the axial direction using two-layer coating flow. The constitutive equation of motion has been solved by using optimal homotopy asymptotic method (OHAM) for ...

New experiments on the orientation of a cylinder settling in viscoelastic and pseudoplastic fluids are described in an attempt to identify the main mechanisms which control the orientation of the cylinder as it falls.

flow characteristics and rheological parameters of “malas yazdi” pomegranate (punica granatum l.) juice were investigated using rotational viscometer at different temperatures (10, 20, 30, 40, 50, 60 and 70ºc) and concentrations (12, 22, 32, 42 and 52º brix). the experimental data had the best fitness with herschel-bulkley model and the values of flow behavior index (n) varied between 0.97 and ...
