3A) Explain in detail how the vortex panel/source panel method will solve the aerodynamics problems for arbitrary shape and thickness in order to calculate the aerodynamic characteristics. Students can explain through step-by-step procedures with the help of graphical illustrations (4 Marks).
3B) By understanding the fundamental thin aerofoil theory for panel method (vortex or source panel method), find one recent literature on the research work that has used this fundamental theory to solve complex engineering problems, especially in the field of aerodynamics.
