Abstract:
Coalescence of liquid drops is a widely observed phenomenon across a diverse range of natural and industrial processes, ranging from the formation of raindrops and the growth of tumor cells to inkjet printing. The physics involved in this seemingly simple process of coalescence is far from simple, and the rheological complexity of the fluid under investigation makes the problem even more challenging. The present article provides a brief overview of existing knowledge on this topic and discusses the potential avenues for future research. Special attention is given to non-Newtonian fluids and soft materials, which exhibit distinct behaviors compared to Newtonian liquids, revealing fascinating deviations that demand deeper investigation.

Capillarity in Fluid
Surface tension is crucial to capillarity. It results from cohesive forces between liquid molecules at the liquid-air boundary, forming a skin that resists external forces. When the capillary tube...

Intermolecular Forces in Solutions
When the strengths of the intermolecular forces of attraction between solute and solvent species in a solution are no different than those present in the separated components, the solution is formed with no accompanying energy change. Such a solution is called an ideal solution. A mixture of ideal gases (or gases such as helium and argon,...
