Drop coalescence is central to diverse processes involving dispersions of drops in industrial, engineering, and scientific realms. During coalescence, two drops first touch and then merge as the liquid neck connecting them grows from initially microscopic scales to a size comparable to the drop diameters. The curvature of the interface is infinite at the point where the drops first make contact...

In this work the model of droplets coalescence in liquid/liquid dispersions in flow through fibrous media is proposed. It is derived for the computation cell being a cubicoid that comprises a single mesh gap and equal volumes upstream and downstream, which size corresponds to a packing factor of the filter media. The numerical approach takes into account deposition of droplets on the fibres as ...

Consider a critical Erdos–Rényi random graph: $n$ is the number of vertices, each one $\tbinom{n}{2}$ possible edges kept in graph independently from others with probability $n^{-1}+\lambda n^{-4/3}$, $\lambda $ being fixed real number. When goes to infinity, Addario-Berry, Broutin and Goldschmidt (Probab. Theory Related Fields 152 (2012) 367–406) have shown that collection connected components...

Aerosol reactors pass through regimes where subsets of the population balance terms are dominant. Initially, mixing, reaction, nucleation and accretional growth dominate. This is generally followed by a regime in which coagulation and coalescence control evolution of the particle population into sintered aggregates. Conventionally, the boundary between regimes where coalescence is or is not imp...

A time varying space-time metric is shown to be a source of electromagnetic radiation even in the absence of charge sources. The postNewtonian approximation is used as a realistic model of the connection between the space-time metric and a time varying gravitational potential. Large temporal variations in the metric from the coalescence of relativistic stars are shown to be likely progenitors o...

Galaxy mergers are crucial to understanding galaxy evolution, therefore we must determine their observational signatures select them from large IFU samples such as MUSE and SAMI. We employ 24 high-resolution idealised hydrodynamical merger simulations based on the "Feedback In Realistic Environment" (FIRE-2) model observability of various configurations stages using synthetic images velocity ma...

A time varying space-time metric is shown to be a source of electromagnetic radiation. The post-Newtonian approximation is used as a realistic model of the connection between the space-time metric and a time varying gravitational potential. Large temporal variations in the metric from the coalescence of colliding black holes and neutron stars are shown to be possible progenitors of gamma ray bu...

blown bitumen (110/10) was mixed with heavy vacuum slops (h.v.s), 60/70 penetration grade bitumen and recycled isotactic polypropylene (ipp) at different levels. the resulting resins were used to impregnate non-woven poly(ethylene terephthalate) fibers to form composites. the modulus and penetration grade of the resulting bituminous resins were determined. it was found that these bituminous res...

We find that a simple extension of the coalescence model is sufficient to incorporate the perfect quark number scaling behavior of the elliptic flow in transverse kinetic energy, recently discovered by the PHENIX Collaboration. The flavor dependence of the elliptic flow can be consistently described in the low and intermediate pT if the transverse kinetic energy is conserved in the 2 → 1 or 3 →...

Coalescence of binary supermassive black holes (SBHs) would constitute the strongest sources of gravitational waves to be observed by LISA. While the formation of binary SBHs during galaxy mergers is almost inevitable, coalescence requires that the separation between binary components first drop by a few orders of magnitude, due presumably to interactions of the binary with stars and gas in a g...
