Question

Consider two different flows over geometrically similar airfoil shapes,
one airfoil being twice the size of the other. The flow over the smaller
airfoil has freestream properties given by T_∞ = 200 K, ρ_∞ = 1.23 kg/m³,
and V_∞ = 100 m/s. The flow over the larger airfoil is described by
T_∞ = 800 K, ρ_∞ = 1.739 kg/m³, and V_∞ = 200 m/s. Assume that
both μ and a are proportional to T ^1/2. Are the two flows dynamically
similar?
