← ScienceWhich outcome results involving a submerged drone when laminar flow transitions to turbulent flow?
A)Decreased skin friction drag force
B)Increased boundary layer thickness✓
C)Reduced energy dissipation effects
D)Minimized vortex shedding frequency
💡 Explanation
Turbulent flow increases boundary layer thickness because increased mixing via momentum diffusion enlarges it; this transition happens at a critical Reynolds number. The thickness increases, therefore, rather than, reducing vortex shedding as skin friction drag increases.
