← ScienceWhich 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.
