WebAccording to Chen et al. (2014), the unsteady aerodynamic forces (lift and drag coefficients) around the test model surface, estimated by the surface pressure distributions, can be integrated using the following formulas: (1) C D = 1 2 ∑ i C p i ⋅ Δ θ i ⋅ c o s θ i, C L = 1 2 ∑ i C p i ⋅ Δ θ i ⋅ s i n θ i, C p i = 2 ( p i − p ∞) ρ U 0 2, where C … how to make a picture more clear on pc

WebQuestion: For the Rankine half-body determine the pressure coefficient on the stagnation streamline at the point immediately above the source (i.e. in a direction normal to the free stream velocity). You are given the source strength, 56m?s=1, and the stream velocity, 13ms-1. Please give your answer to 3dp. Show transcribed image text Expert Answer Webis the stagnation specific volume, and Pt is the stagnation pressure. For the adiabatic flow of an ideal gas, this may be integrated to the following expression, with R as the appropriate gas constant: (s2 s1) R ln(Pt2 Pt1). (18) Hence, given the experimental value for the decrease in stagnation pressure across the expansion, WebThe streamlines along with the location of the stagnation point for different dimensionless circulation strengths ( Γ / [2πaU] ) are shown in the figure. The pressure distribution along the cylinder surface can be obtained by Bernoulli's equation, giving . This is generally rearranged in terms of the dimensionless pressure coefficient, C p, how to make a picture less compressed
