Which risk increases when using iterative complex mathematical modeling for turbulent fluid flow?

A)Numerical instability dominates the flow
B)Reynolds number suddenly drops precariously
C)Kinetic viscosity nears absolute minimum
D)Eddy diffusivity becomes completely isotropic

💡 Explanation

Because iterative solvers approximate solutions of Navier-Stokes via successive approximations, numerical instability escalates due to rounding errors overwhelming the physical models. Therefore instability arises, rather than Reynolds number changes, because these models simulate but do not alter physical constants.
