Fig. 3From: Numerical study of the square-root conformation tensor formulation for confined and free-surface viscoelastic fluid flowsNumerical simulation of the lid-driven cavity flow using the Oldroyd-B model for \(Re=0.01\) and \(\beta =0.5\). The non-Newtonian component of the dimensionless normal stress \(\frac{\tau _{xx}^{'}}{\eta _{0}U/L}\) is plotted along the vertical line \(x=0.5\) for a \(Wi=1\) and b \(Wi=2\) Back to article page
