Which consequence results when fluid dynamic choke flow in a rocket's venturi nozzle transitions to fully developed turbulence?

💡 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.
