Consider again the model truck example, except that the maximum speed of the wind tunnel is only
Question:
Consider again the model truck example, except that the maximum speed of the wind tunnel is only 50 m/s. Aerodynamic force data are taken for wind tunnel speeds between V = 20 and 50 m/s—assume the same data for these speeds as those listed in Table 7–7. Based on these data alone, can the researchers be confident that they have reached Reynolds number independence?
