Jumping sundogs, or crown flashes, are a rare and interesting atmospheric phenomenon characterized by beams of light dancing across the sky. Despite their rarity, social media videos have captured numerous instances this under seemingly similar conditions. By analyzing these videos, we investigated structure dynamics jumping sundogs. Our analysis reveals that events require specific ice crystal types The distinctive feather-like luminescence sundogs is attributed to orientation crystals...

We studied the formation dynamics of air bubbles emitted from a nozzle submerged in aqueous glycerol solutions different viscosities. describe evolution bubbling regimes by using flow rate as control parameter and time between successive dynamical variable. Some results concerning coalescence were emulated with combination simple maps. also observed shells surrounding liquid drops inside liquid, known antibubbles. The antibubbling conditions related to an intermittent regime.

Jumping sun dogs are rapid light flashes changing over clouds, with some of them located close to the places halo formation in thunder storms clouds. This paper presents an outline aspects that required for understanding jumping dogs, using experiments scattering complex fluids. In our analogy, we have observed laser which ice crystals replaced by needlelike structures ferrofluid, electric field atmosphere is represented external magnetic field, and beam scattered ferrofluid structure has...

We are presenting an experimental setup based on polarized light, enabling the visualization of magnetic field assemblies using a Hele-Shaw cell filled with ferrofluids. have simulated observed patterns hypergeometric polynomials.

Chains of bubbles are seen rising along the wall whenever champagne is poured into a glass. The careful observation given bubble chain often reveals that interbubble distance suddenly changes during degassing process, indicating different bubbling regimes in this elusive phenomenon effervescence. We report transitions between these present sequences multiple periods known as period-adding route.

We obtained period-adding bifurcations in a bubble formation experiment. Using the air flow rate as control parameter this experiment, emission from nozzle viscous fluid undergoes single bubbling to sequence of periodic k k+1 periods, occasionally interspersed with some chaotic regions. Our main assumption is that bifurcation depends on variations chamber under nozzle. This was experimentally tested by placing tube between reservoir and column By increasing length, more were observed....

This study explored the complex relationship between magnetic fields and light polarization in thin films of ferrofluid. Utilizing techniques such as polarized imaging, multipolar expansion, Mueller matrix formalism, this work investigated formation isogyres, which are distinct patterns observed when passes through ferrofluid under various field configurations. The analysis revealed that alignment nanoparticles response to resulted a diffraction grating, influencing polarization. Through...

We studied the effects of image formation in a device known as Ferrocell, which consists thin film ferrofluid solution between two glass plates subjected to an external magnetic field presence light source. Following suggestions found literature, we compared Ferrocell scattering for some configurations with conical by structures foams Plateau borders, and discuss this type concept diffracted rays from Geometrical Theory Diffraction. For certain configurations, point source creates images...

Observing the light passing through a thin layer of ferrofluid, we can see occurrence interesting effects, both in formation patterns within ferrofluid and dispersion outside that layer. This leads us to ask what explanations associated with these effects are. In this paper, analyze explain luminous using Ferrolens, commercially known as Ferrocell.

We obtain experimental data on time intervals of a bubble train generated from nozzle with the air flow rate as control parameter. Varying length hose that connects proportionating solenoid valve to nozzle, we generate bifurcation diagrams showing period-adding cascades, among other dynamical phenomena. Then construct two-parameter family one-dimensional maps whose qualitatively match ones. The model indicates existence parameters where two attractors coexist, phenomenon called bistability,...

Bubble trains are seen rising gracefully from a few points on the glass wall (called nucleation sites) whenever champagne is poured into glass. As time passes during gas-discharging process, careful observation of some given bubble columns reveals that interbubble distance may change suddenly, thus revealing different rhythmical bubbling regimes. Here, it reported transitions between regimes sites gas discharging process which be ruled by strong interaction tiny pockets trapped inside site...

Liquid foams have fascinating optical properties, which are caused by the large number of light refractions and reflections liquid films Plateau borders. Due to refraction reflection at interfaces, direction rays leaving a border can vary greatly for same incident angle small positional offset. A close look in some configurations borders or bridges reveals existence triangular patterns surrounded complex structure, these bear resemblance those observed systems involving chaotic scattering...

We have explored some features of the complex fluids present in Earth’s atmosphere by observation optical phenomena and compared them to observed gems magnetic materials. The main feature a fluid is that it contains polyatomic structures such as polymer molecules or colloidal grains.

We present an experimental investigation of the agglomeration bubbles obtained from a nozzle working in different bubbling regimes. This experiment consists continuous production at bottom liquid column, and these create two-dimensional (2D) foam (or bubble raft) top this column. The can assemble various dynamically stable arrangement, forming kinds foams mixture water glycerol, with effect that formation regimes influence bubbles. average number is related to frequency mean lifetime....
