Abstract
A comparison between Full Potential and Euler numerical solutions for 2D transonic unsteady flow is presented. The pros and cons of the pote ntial model are discussed and the main features of both computational methods are summarised. The comparison is done for a Naca 0012 aerofoi l oscillating in pitch at a freestream Mach number ranging from 0.755 to 0.825, in order to investigate the limit of application of the pote ntial approximation in an unsteady flow.
