Spreading and Imbibition of Viscous Liquid on a Porous Base
Stephen H. Davis,L. M. Hocking +1 more
TL;DR: In this article, the competition between the viscous spreading of liquid on a substrate and the absorption by the substrate is studied using several models, including the local behaviors near the contact lines, the time scales of droplet spreading and disappearance, and the dependencies on the physical factors that enter.

Heat transfer analysis in multi-layered materials with interfacial thermal resistance
TL;DR: In this paper , two one-dimensional models are developed for the heat transfer analysis in multi-layered materials with ITR, one is to create a virtual layer at the interface to represent the ITR and the other is to use a local artificial layer surrounding the interface with modified thermal properties to reflect the influence of ITR on heat transfer in the layer involving the interface.

Quantifying the dynamic spreading of a molten sand droplet using multiphase mesoscopic simulations
Rahul Koneru,Alison B. Flatau,Zhen Li,Luis Bravo,Muthuvel Murugan,Anindya Ghoshal,George Em Karniadakis +6 more
TL;DR: In this article , the authors studied the wetting dynamics of a highly viscous molten sand droplet on a smooth substrate and observed a universal contact line spreading, independent of the droplet size, with the characteristic inertial and viscous spreading regimes.

Drop Impact Dynamics: Splashing, Spreading, Receding, Bouncing ...
TL;DR: In this article, a review deals with drop impacts on thin liquid layers and dry surfaces, referred to as splashing, and their propagation is discussed in detail, as well as some additional kindred, albeit nonsplashing, phenomena like drop spreading and deposition, receding (recoil), jetting, fingering, and rebound.
