← ScienceWhich consequence results when modeling aerodynamic drag using Gaussian functions neglects a fluid’s viscosity?
A)Lower boundary layer separation estimates✓
B)Increased computational fluid dynamics iterations
C)Overestimation of turbulent kinetic energy
D)Elevated pressure gradients near surfaces
💡 Explanation
Lower boundary layer separation occurs because Gaussian functions approximate inviscid flow by ignoring viscosity. Therefore, neglecting viscosity diminishes frictional effects, rather than accurately modeling them; this causes less pressure buildup and underestimation of real separation distances.
