 ## Description
 
 The dataset captures the time-evolving behavior of 3D spherical droplets subjected to an external shock wave in air.
-The interaction with the shock wave results in two different breakup-modes of the droplet (SIE and RTP). 
+When a shock wave impacts a droplet, the initial response—largely independent of the Weber number—is a deformation phase in which the droplet flattens.
+This interaction with the shock wave results in two different breakup-modes of the droplet (SIE and RTP).
+In the SIE regime, breakup is driven mainly by strong shear forces acting along the droplet surface. 
+After the droplet has flattened, shear-induced disturbances emerge near the equator; these instabilities originate near the droplet equator after the droplet has flattened out in the first phase and are advected along the droplet surface. 
+As the relative velocity between the droplet and the surrounding gas increases, these disturbances grow due to Kelvin–Helmholtz instability, eventually stripping liquid from the droplet and producing fine droplets downstream. 
+In contrast, in the RTP regime, relatively stronger surface tension suppresses the growth of such shear instabilities, maintaining a smoother interface. 
+As deformation progresses, the upstream side of the droplet becomes concave as the surrounding gas penetrates and pierces the liquid. 
+Unlike RTP, the SIE regime is characterized by a continuous and gradual loss of mass, often resulting in a mist of droplets downstream.
 Here we investigate a scenario with symmetric boundary conditions at the north, south, top and bottom walls.
