Shear rate projection schemes for non-Newtonian fluids

Abstract: The operator splitting approach applied to the Navier-Stokes equations, gave rise to various numerical methods for the simulations of the dynamics of fluids. The separate work of Chorin and Temam on this subject gave birth to the so-called projection methods. The basic projection schemes, either the incremental or non-incremental variant (see [1]) induces an artificial Neumann boundary condition on the pressure. By getting rid of this boundary condition on the pressure, the so-call rotational incremental press… Show more

“…Muhammad et al [24] studied Carreau nanofluid under the influence of slip over a wedge with motile microorganisms and thermal radiation effects. Besides, these many scientists carried to analyze the stagnation point flow and other non-Newtonian fluids with aspect to the following citations, provided a detailed view of flows [25][26][27][28][29][30][31][32][33].…”

“…Nonetheless, most stabilisation methods are based on perturbed incompressibility equations devised under classical Newtonian assumptions. Probably for that reason, the use of LBB-compatible finite elements is somewhat more frequent in the literature for quasi-Newtonian fluids [6][7][8][9][10][11][12][13][14][15][16]. Although such compatible spaces offer an ideal setting from a theoretical standpoint, they are not always viable options.…”

“…In view of these challenges, one might prefer projection or split-step schemes decoupling velocity and pressure [13,14], thereby decomposing the system into convection-diffusion, Poisson and simple mass matrix problems. Nonetheless, projection methods suffer from artificial pressure boundary conditions (refer to Guermond et al [15] for an excellent overview), which often call for corrective measures [16,17].…”

“…While schemes of similar kind have been applied to challenging incompressible flow problems [19][20][21][22], the extension to the non-Newtonian case is in many aspects challenging. Deteix and Yakoubi [14] proposed the so-called shear rate projection scheme which, despite being accurate and simple, requires LBB-stable velocity-pressure pairs and the solution of an advection-diffusion equation, two Poisson problems and more than ten scalar mass matrix problems per time step.…”
