← ScienceWhich consequence results when a fluid's viscosity assumption breaks down in a Navier-Stokes equation simulation?
A)Inaccurate pressure gradient prediction✓
B)Precise laminar flow visualization
C)Stable transient thermal solution
D)Reliable multiphase interface resolution
💡 Explanation
In Navier-Stokes, the viscosity assumption breakdown leads to errors in the Pressure Gradient Calculation because the equations simplify viscous forces. Therefore, the simulation yields incorrect velocities rather than accurately modelling the real-world fluid; this leads to numerical divergence in complex geometries.
