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 give by T[infinity] = 200K, rho[infinity] = 1.23kg/m3 , and U[infinity] = 100m/s. The flow over the larger airfoil is described by T[infinity] = 800K, rho[infinity] = 1.739kg/m3 , and U[infinity] = 200m/s. Assume that both µ (dynamic viscosity) and a (speed of sound) are proportional to T 1/2 . Are the two flows dynamically similar
