Multi-scale modeling of expanding plasmas is crucial for understanding the dynamics and evolution of various astrophysical plasma systems such as the solar and stellar winds. In this context. the Expanding Box Model (EBM) provides a valuable framework to mimic plasma expansion in a non-inertial reference frame. co-moving with the expansion but in a box with a fixed volume. https://poolsproductscanadas.shop/product-category/pentair-e-z-vac-parts/
