  title={Nonlinear analysis of G{\"o}rtler vortices},
  author={Yoshitada Aihara},
An integral method of analysis is applied to investigate the Gortler vortices in the nonlinear region, and the following results are obtained: (1) The neutral stability diagram obtained for small amplitude vortices shows reasonable agreement with the results of linearized theory by Gortler, Hammerlin, and Smith. (2) A possible analytical prediction of unsteady meandering motion of vortices is discussed. (3) The stable finite amplitude of Gortler vortices is achieved associated with some… CONTINUE READING
