Abstract Details

2014, Master of Science in Engineering (MSEgr), Wright State University, Mechanical Engineering.
The goal of this study is to validate the accuracy of the SC/Tetra CFD code by modeling four cases: a 2D zero pressure gradient flat plate, an axisymmetric separated boundary layer, flow over an NACA 0012 airfoil, and flow over an NACA 4412 airfoil trailing edge separation. The results will be compared to experimental data and CFL3D results. This study also investigates the sensitivity of SC/Tetra results to different set up details such as mesh resolution, turbulence model, and under-relaxation settings. Automation using the Visual Basic programming language was used to vary these set up details and efficiently process a large number of simulations for NACA 0012. The Flat plate case focuses on skin friction coefficient and velocity profiles. The axisymmetric separated boundary layer case concentrates on pressure coefficient and velocity profiles. For the NACA 0012 airfoil, evaluation focuses on Cp profiles. Cp and velocity profiles and streamlines are considered for the NACA 4412 airfoil. In general, coarser meshes are shown to be less accurate than finer meshes and the SST k-OMG is more accurate.
