Dust destruction efficiencies (left y-axis) and masses (right y-axis) in the z = 0 slice. This destruction efficiency refers to the ratio of the destroyed dust mass at each time step to the total encountered dust mass at the last considered snapshot. Different Mach numbers of ℳ = 0, 0.3, 1, and 3, and average ISM densities of n = 1, 10, and 100 cm⁻³ are shown. For each Mach number and ISM density parameter set, four different dust simulations were carried out, including either silicate (Sil) or carbonaceous (Car) dust, and either grain–grain collisions and sputtering (gg+sp) or only sputtering (sp).
