Investigation of the Richtmyer-Meshkov instability using digital holography in the context of catastrophic aerobreakup

M. M. Mansoor et al.

Summary: We conducted shock tube experiments with high-speed digital holography to study the Richtmyer-Meshkov instabilities on an air-sulfur hexafluoride gaseous interface and better understand the formation of windward surface waves during catastrophic hydrometeor aerobreakup. By using a gaseous interface created with a bubble film, we achieved similar instability patterns with much lower shock strength, allowing for simpler and safer laboratory tests with high resolution data. Our findings suggest potential applications in controlling catastrophic aerobreakup in hypersonic flight under adverse weather conditions.

Depth from defocus technique applied to unsteady shock-drop secondary atomization

Shubham Sharma et al.

Summary: The two-sensor depth from defocus technique is developed to achieve higher spatial and temporal resolution, improve estimates of spatial size distribution and number concentration, and provide guidelines for the calibration and design of optical systems. The technique and improvements are demonstrated in the case of secondary atomization with a shock wave and a single drop, where high-resolution number density and size distributions of secondary droplets are necessary.

Rheocoalescence: Relaxation Time through Coalescence of Droplets

Sarath Chandra Varma et al.

Summary: This study investigates the formation and development of neck droplets during coalescence using high-speed imaging. Based on the concentration ratio, three different regimes are identified, and it is found that the growth of the neck droplet radius follows different power-law behavior. A new measurement technique is proposed based on the dependence of the power-law exponent on concentration ratios, which can potentially predict the relaxation time of fluids in the elasticity dominated regime.

Coalescence of polymeric sessile drops on a partially wettable substrate

Sarath Chandra Varma et al.

Summary: The coalescence of sessile polymeric fluid drops on a partially wettable substrate undergoes a transition from the inertial to viscoelastic regime at a concentration ratio c/c* around 1. The temporal evolution of the growing bridge height follows a power law behavior, with the coefficient b decreasing continuously from 2/3 in the inertial regime to an asymptotic value of 1/2 in the viscoelastic regime. A modified thin film equation, incorporating fluid elasticity and characteristic timescale in the viscoelastic regime, has been proposed to account for this behavior, and numerical results show good agreement with experimental data.

On secondary atomization and blockage of surrogate cough droplets in single- and multilayer face masks

Shubham Sharma et al.

Summary: Face masks can prevent the transmission of infectious respiratory diseases by blocking large droplets and aerosols. Single or double-layer masks may not effectively block the penetration of large droplets, leading to their atomization into smaller droplets that can remain airborne. Therefore, three-layer masks may be more effective in preventing the spread of these droplets.

Effects of elasticity number and time constant ratio on breakup and droplet formation of viscoelastic planar liquid sheet co-flowing with gases of equal velocities

Debayan Dasgupta et al.

Summary: The study explores the effects of velocity ratios, elasticity numbers, and time constant ratios on the stability of a viscoelastic liquid sheet. It finds that the interactions between these parameters can lead to dual effects, influencing the formation of droplets of different sizes. The results highlight the complex relationships between various parameters in determining the behavior of the liquid sheet.
