← ScienceWhich consequence results when fluid dynamic choke flow in a rocket's venturi nozzle transitions to fully developed turbulence?
A)Increased nozzle thrust efficiency
B)Decreased propellant flow rate
C)Elevated combustion chamber pressure
D)Reduced ablation cooling effectiveness✓
💡 Explanation
Reduced ablation cooling results, because turbulent flow disrupts the laminar boundary layer maintained by ablation. Therefore, the exhaust stream contacts the nozzle wall directly rather than flowing along the cooling surface; ablation declines, rather than increasing thrust.
