Burning Properties of Slurry Based on Coal and Oil Processing Waste
TL;DR: In this paper, the main physicochemical coefficients of the components and of the tested coal-water slurry containing petrochemicals (CWSP) have been collected, and the viscosity, mixture stability, density, ash content, humidity, flash and ignition temperatures, and enthalpy of combustion of tested CWSP are reported.

The effect of Weber number, droplet sizes and wall roughness on crisis of droplet boiling
TL;DR: In this paper, various boiling modes in a wide range of droplet sizes and wall temperature under droplet T w, Weber number We, wall roughness and droplet shape were studied experimentally.
Journal ArticleDOI
Evaporation, boiling and explosive breakup of heterogeneous droplet in a high-temperature gas
TL;DR: In this paper, an experimental investigation of evaporation and boiling was carried out on fixed water droplet containing a single nontransparent solid inclusion and placed in gaseous environment at high-temperature (500-1100 K).
Journal ArticleDOI
Influence of droplet concentration on evaporation in a high-temperature gas
TL;DR: In this article, the evaporation of water droplets with initial sizes from 100μm to 300μm was studied in high temperature gas counter flow with velocity of about 1.5m/s at temperature of about 1100 K. The gas in this study is a mixture of air and combustion products of kerosene.
Journal ArticleDOI
Wall effect on heat transfer crisis
TL;DR: In this article, a wide range of droplet sizes and wall temperatures at a change in thermal-physical and geometrical characteristics of the wall were studied experimentally in different evaporation regimes, taking into account free convection of gas and thickness of diffusion boundary layer.

Physics of liquid jets
Jens Eggers,Emmanuel Villermaux +1 more
TL;DR: A review of the fundamental and technological aspects of these subjects can be found in this article, where the focus is mainly on surface tension effects, which result from the cohesive properties of liquids Paradoxically, cohesive forces promote the breakup of jets, widely encountered in nature, technology and basic science.

Fundamentals of digital particle image velocimetry
TL;DR: In this paper, the measurement principle of digital particle image velocimetry (PIV) is described in terms of linear system theory and conditions for PIV correlation analysis as a valid interrogation method are determined.

Coalescence and separation in binary collisions of liquid drops
Nasser Ashgriz,J. Y. Poo +1 more
TL;DR: In this article, an extensive experimental investigation of the binary collision dynamics of water drops for size ratios of 1 075 and 05, for the Weber-number range of 1 to 100, and for all impact parameters is reported Two different types of separating collisions, namely reflexive and stretching separations, are identified.

Universal pinching of 3D axisymmetric free-surface flow
TL;DR: This work considers the viscous motion of an axisymmetric column of fluid with a free surface and the Navier-Stokes equation forms a singularity as the height of the fluid neck goes to zero.

The bifurcation of liquid bridges
TL;DR: In this article, the shape of the liquid bridge joining a nascent water drop to its parent body is presented for times before, after and at the instant of bifurcation when the drop is created and also when the secondary droplet is formed.
