Helmholtz velocity decomposition
Web26 feb. 2024 · I need Helmholtz decomposition to separate the solenoidal and dilatational velocity fields. This is the decomposition I am following (according to Wikipedia) where A is a vector field, and Phi is a scalar field. I wrote my own code in MATLAB. Here is a pseudo-code for solving the Poisson equation resulting from the Helmholtz … WebHelmholtz decomposition of horizontal velocity u for the terrestrial simulation at 0.4 bar. Left panel: Rotational component of u, r. Fig.3shows that this component is composed of the zonal-mean eastward equatorial jet and a stationary wave with zonal wavenumber 1. Right panel: Divergent component of u, u d.
