In Magnetohydrodynamics, the Hasegawa-Mima equation appears as a model for pseudo three-dimensional turbulence of a confined plasma inside a Tokamak reactor. This equation bears close resemblence to the 2d Navier-Stokes ...
Hasegawa-Mima was derived by Akira Hasegawa and Kunioki Mima during late 70s. When normalized, it can be put as the following PDE that is third order in space and first order in time: ∆ u_t + u_t={u, ∆ u} +{p,u}
In a ...
