On the generation of drift flows in wall-bounded flows transiting to turbulence
Theoretical and Applied Mechanics Letters, 2018 : Despite recent progress, laminar-turbulent coexistence in transitional planar wall-bounded shear flows is still not well understood. Contrasting with the processes by which chaotic flow inside turbulent patches is sustained at the local (minimal flow ...

Steady flow of power-law fluids in a 1:3 planar sudden expansion [PDF]
, 2013 The laminar flow of inelastic non-Newtonian fluids, obeying the power-law model, through a planar sudden expansion with a 1:3 expansion ratio was investigated numerically using a finite volume method. A broad range of power-law indices in the range 0.2 n

Shear stress in arterial stenoses : a momentum integral model [PDF]
, 1998 A mathematical model is developed to investigate blood flow in arterial stenoses up to Reynolds numbers of 1000. The approach is based on Thwaites' method, normally used to treat laminar boundary layer development over a body in a freestream.
