Consider two different flows over geometrically similar airfoilshapes, one airfoil beingtwice the size of the other. Also, assume that the angle of attackis the same in bothflows. The airflow over the smaller airfoil has freestreamproperties given by 𝑇,=200 𝐾, 𝜌,= 1.23 𝑘𝑔 𝑚-⁄ , and 𝑉,= 100 𝑚 𝑠⁄ . The airflow over thelarger airfoil isdescribed by 𝑇,= 800 𝐾, 𝜌,= 1.739 𝑘𝑔 𝑚-⁄ , and 𝑉,= 200 𝑚 𝑠⁄ .Assume that theviscosity of the air is proportional to 𝑇.!⁄, while the heatcapacities of air is constant.Are the two flows similar?
