Which condition is indicated when calculating high Reynolds number past bluff body?

A)Transition to turbulent flow regime
B)Dominance of viscous forces
C)Laminar flow is well-defined
D)Fluid compressibility is negligible

💡 Explanation

High Reynolds number signifies inertial forces dominate over viscous forces; therefore separation occurs and the flow experiences transition to turbulent flow, because increased kinetic energy amplifies instabilities, rather than remaining laminar or dominated by viscosity.
