← ScienceWhich outcome results when the assumption of inviscid flow is applied too liberally in computational fluid dynamics modeling of an aircraft wing?
A)Elevated drag coefficient predictions arise
B)Lowered computational resource requirements emerge
C)Delayed stall angles become apparent✓
D)Precise surface pressure distributions form
💡 Explanation
The boundary layer separates later than predicted because the Kutta condition, affected by viscosity, isn't properly accounted. Therefore, the predicted stall angle is delayed, rather than pressure is accurate, because viscous forces are omitted from the computations.
