Please do it carefully and all the three parts I'll like your solution
Consider the flow case an external flow around NACA64-618 aerofoil. The flow conditions are available in following Table. Using flow aerodynamics knowledge and above 'law of the wall': (1) Determine the flow status, such as laminar or turbulent flow, compressible or incompressible flow. (2) Choose the right boundary layer thickness calculation formula; and estimate its value to be used in meshing procedure. (3) For a structured/hybrid mesh generation for the case, the accurate wall distance and inflation layer information based on a user determined y+ value are required. Please follow the guidance from ME7724 lectures or general CFD theory to obtain this information for meshing procedure (all formula and calculation details should be included); explain your choice of the y+ value in terms of the boundary layer flow physics; Demonstrate that inflation layers properly reflect the physical viscous layer. #3 Airfoil le (m) Uo (m/s) Too (K); Po (kg/m³); pœ∞ (Pa); µ (kg/ms) a.° 1 NACA64-618 0.6 45.03 317.6; 1.018; 92810; 1.9234E-5
