Which consequence results when cooling airflow over a turbine blade exceeds the critical Reynolds number?

A)Laminar-turbulent transition increases dramatically
B)Blade material undergoes phase transition
C)Creep strain rates accelerate
D)Thermal conductivity decreases exponentially

💡 Explanation

Beyond the critical Reynolds number, laminar flow transitions into turbulent flow because increased momentum transfer causes boundary layer separation; therefore, transition increases dramatically, rather than the other thermal or material effects which occur through different mechanisms.
