Test and Simulation Design: The purpose of CFD lab 2 is to use the ANSYS software used in CFD lab 1 and conduct parametric studies for turbulent flow around Clark-Y airfoil. This is the same as EFD lab 3 except this time the CFD process will be used and the test simulation will be done using Workbench software. The effect of angle of attack will be tested in this lab. CFD Process: The first part of the CFD process is to design the geometry of the part. For this lab, the airfoil geometry was created on the class website and implemented in the ANSYS software. The first action done was to take the airfoil geometry downloaded and rotate it 16 degrees so lift can be simulated. A circle with a diameter of 12 m was then drawn around the airfoil geometry was created and the airfoil shape was then subtracted from the circle. The circle was then split into 4 different sections so the meshing can be easier. The next step in the CFD process is mesh. Face meshing was applied to the four surfaces. Then, sizing was applied to the 4 different edges created. The right half of the circle was split into 45 degrees and the left side was set to 60 divisions. The lines leading to the airfoil geometry were set to 115 divisions with a bias factor of 5000. After all the sizing parameters were set, the details of the mesh were set to CFD and the mesh was generated. Physics is the next step in this lab process. The simulation was set to a laminar flow for both the K-e and K-w models but the model constants were different. The material was set to air and the density and viscosity for the simulation was set based on the data gathered in EFD lab 3 data reduction sheet. Next, the boundary conditions were applied for each model. The x-velocity
