“…14,15 Another solution is to use the Rhie-Chow interpolation method 16 with the collocated arrangement of unknowns. It is standard in industrial applications such as CD-Adapco STAR-CCM, 17 Ansys CFX, 18 Ansys Fluent, 19 Converge CFD. 20 It is also employed in widely used OpenFOAM package using implicit fully coupled approach 21 and later extended to moving meshes.…”

In this work, we develop numerical methods for the solution of blood flow and coagulation on dynamic adaptive moving meshes. We consider the blood flow as a flow of incompressible Newtonian fluid governed by the Navier–Stokes equations. The blood coagulation is introduced through the additional Darcy term, with a permeability coefficient dependent on reactions. To this end, we introduce moving mesh collocated finite‐volume methods for the Navier–Stokes equations, advection–diffusion equations, and a method for the stiff cascade of reactions. A monolithic nonlinear system is solved to advance the solution in time. The finite volume method for the Navier–Stokes equations features collocated arrangement of pressure and velocity unknowns and a coupled momentum and mass flux. The method is conservative and inf‐sup stable despite the saddle point nature of the system. It is verified on a series of analytical problems and applied to the blood flow problem in the deforming domain of the right ventricle, reconstructed from a time series of computed tomography scans. At last, we demonstrate the ability to model the coagulation process in deforming microfluidic capillaries.

“…It is noted that as AR increases, the number of primary vortices increases and the direct percolation of the flow is not significantly affected by the moving lids. Marković et al [31] performed a numerical simulation of two-sided lid-driven flow inside a staggered cavity by using the commercial software ANSYS FLUENT. Fundamentally, in antiparallel wall motion, their results show symmetrical and asymmetrical steady flow patterns for the variety of Re ranges from 50 to 1000, while the obtained steady solutions for parallel wall motion show only asymmetrical flow patterns for the whole range of Re.…”

The two-dimensional asymmetrical flow in a two-sided lid-driven square cavity is numerically analyzed by the finite volume method (FVM). The top and bottom walls slide in parallel and antiparallel motions with various velocity ratio (UT/Ub=λ) where |λ|=2, 4, 8, and 10. In this study, the Reynolds number Re1 = 200, 400, 800 and 1000 is applied for the upper side and Re2 = 100 constant on the lower side. The numerical results are presented in terms of streamlines, vorticity contours and velocity profiles. These results reveal the effect of varying the velocity ratio and consequently the Reynolds ratio on the flow behaviour and fluid characteristics inside the cavity. Unlike conventional symmetrical driven flows, asymmetrical flow patterns and velocity distributions distinct the bulk of the cavity with the rising Reynolds ratio. For λ>2, in addition to the main vortex, the parallel motion of the walls induces two secondary vortices near the bottom cavity corners. however, the antiparallel motion generates two secondary vortices on the bottom right corner. The parallel flow proves affected considerably compared to the antiparallel flow.
