Pitch & Plunge Simulation (altered openFoam Wing motion tutorial)
I pursued a brief Internship at the National University of Singapore, where a professor introduced me to the subject Aero-elasticity, and as a part of my work I studied Unsteady aerodynamics and the Flutter problem. During my internship time, I performed a very basic pitch & plunge aerofoil simulation, the likeness of which is very similar to that of the 'wing motion' tutorial case found in the openFoam. The idea was to study the separation regions and the force Coefficients. The above equation is represented in the dynamicMeshDict with constraints for pitch along y-axis and plunge about z-axis.
