Study guide for Chapter 1 for the Exam 1 Chapter 1 has introduced a series of important terminology, thoughts, definitions, and concepts, which are essential to the progressive study of aerodynamics. The students are expected to Remembering : The definition and meaning of Mach number, Reynolds number, shear stress, kinematic viscosity, dynamics pressure, pressure coefficient, skin friction coefficient, normal force coefficient, axial force coefficient, moment coefficient, lift coefficient, drag coefficient, center of pressure, angle of attack. stalling velocity, lift-to-drag ratio, zero-lift drag coefficient, freestream flow condition, slip boundary condition, and non-slip boundary condition, aerodynamic heating rate. Understanding: Describe the properties of the fluid: viscosity and compressibility. Describe the meaning of flow variables: density, velocity, pressure, temperature. Describe the flow similarity. Distinguish the difference between a solid and a fluid from the point of view of

Unformatted text preview: dynamics. Explain the generation of lift, drag, and pitching moment on a body from pressure and shear stress distributions. Explain the difference between pressure drag and skin friction drag. Explain the flow separation and transition. Explain the difference between laminar flow and turbulent flow. Describe the assumption for inviscid flows. Describe the assumption for incompressible flows. Interpret Prandtl's boundary layer theory. Applying: Calculate the aerodynamic forces, moments, and coefficients and the center of pressure from pressure and shear stress distributions. Calculate Mach number and Reynolds number from a given flow condition. Analyzing: Derive the aerodynamic coefficients from pressure and shear stress distributions. Evaluating: Determine the necessary conditions in wind tunnel testing to simulate the free-flight conditions based on the dynamic similarity. Determine if two flows are dynamically similar....
