Correction: Quantification of Hydrometeor Breakup in High Weber Number Flows
Abstract
Correction Notice Corrections:1. Section III.B Image Analysis, Page #11, Paragraph #1, Sentence #2 a. "This length scale correction factor, L scale , is obtained by comparing the droplet's major axis and frontal diameter immediately before and after projectile interaction, using frames where breakup has not yet begun." to "This length scale correction factor, L scale , is obtained by comparing the droplet's major axis and frontal diameter immediately before and after the interaction with the projectile's shockwave, using frames where breakup has not yet begun." 2. Section IV Results, Page #14, Paragraph #2, Sentence # Second to Last a. "AR rel (τ ≲ 0.05) ≊ -(1.26 ⋅ τ + 1.0)" to "ΔAR rel (τ ≲ τ A.S. (≈ 0.05)) ≊ -1.26 ⋅ τ + 1.0" 3. Section IV Results, Page #14, Paragraph #3, Sentence #3-END a. "The reason for this can be thought of in two similar ways.The first of which is that the larger aspect ratio droplet presents a more blunt windward face and thus generates a larger stagnation region on the droplet face, and since the droplet is deformable, this increased area leads to a larger deformation due to the increased pressure loading across the frontal surface.In essence, the broader windward face of a high-aspect ratio droplet produces a stronger stagnation pressure and a greater pressure differential between the front and rear surfaces, which accelerates lateral deformation."to "The observed behavior can be interpreted through two complementary mechanisms, one associated with the external gas aerodynamics and the other with the internal liquid mechanics, both governed by the droplet geometry.A higher aspect ratio hydrometeor exhibits nonuniform surface curvature, with extended regions of low curvature located near the top and bottom of the droplet (relative to the flow direction).These low curvature regions correspond to lower local static pressures on the droplet surface, providing an expanded low-pressure region into which the liquid can be driven into as deformation begins from the high pressure at the stagnation point.Concurrently, the local capillary restoring pressure decreases with decreasing surface curvature, reducing the resistance to deformation in these same regions compared to a spherical droplet.The combined effect of an enhanced aerodynamic pressure gradient and diminished capilla ry resistance promotes accelerated deformation, resulting in a more rapid increase in the frontal diameter for higher aspect ratio droplets."4. Section IV Results, Page #15, Paragraph #1, Sentence #2 a. "Subtraction of d 0 /L 0 " to "Subtraction of d/L 0 " 5. Section IV Results, Page #15, Paragraph #2, Sentence #Last a. "This larger surface area will lead to a larger aerodynamic loading on less spherical droplets and thus leads to a more rapid increase in the frontal diameter of the droplets."to "The extended regions of low surface curvature associated with higher aspect ratio droplets enhance both the aerodynamic pressure gradients and the reduction in capillary restoring pressure, thereby promoting a more rapid increase in frontal diameter."6. Section IV Results, Page #19, Figure #13a a.The figure displays the incorrect fit equation; the following has the corrected fit equation.
