Which outcome occurs when Reynolds number exceeds threshold in rocket propellant?

A)Transition towards turbulent combustion instability
B)Propellant density achieves uniform homogeneity
C)Laminar flow stabilizes flame front
D)Speed of deflagration decreases sharply

💡 Explanation

Turbulent combustion instability emerges, because elevated Reynolds number prompts disturbances amplifying in flow. This manifests because the underlying transition to turbulence generates greater mixing, therefore leading to instability, rather than suppressing it, under smoother flow environments.
