WebFeb 1, 2024 · One of such NLEES is the (1 + 1)-dimensional Gardner equation and is formulated by u t + 6 β u x u + u x x x − 3 2 α 2 u 2 u x = 0, that is a mixed version of the well known Korteweg-de Vries (KdV) equation and the modified KdV (mKdV) equation [1], [2]. The Eq. (1)equation is reduced to the KdV and mKdV equation for α = 0 and β = 0 ... WebNov 8, 2013 · Transcritical flow of a stratified fluid past a broad localised topographic obstacle is studied analytically in the framework of the forced extended Korteweg–de Vries, or Gardner, equation. We consider both possible signs for the cubic nonlinear term in the Gardner equation corresponding to different fluid density stratification profiles.
