Which outcome occurs when computational fluid dynamics (CFD) simulations omit viscous effects?

💡 Explanation

Elevated flow rate predictions stem from the omission of fluid's internal friction known as viscosity; thus, the pressure drops are not modeled. Omitting these effects suppresses frictional losses because energy dissipation mechanism of viscosity not considered, therefore, flow rates are elevated rather than reduced, with inaccurate hydrodynamic forces.
