Advances and challenges in explaining fuel spray impingement: How much of single droplet impact research is useful?
TL;DR: In this paper, a critical review of the literature on spray-wall impact relevant to IC engines is presented, in an attempt to address the rationale of describing spraywall interactions based on the knowledge of single droplet impacts.

Effects of surface roughness on water droplet impact history and heat transfer regimes
TL;DR: In this paper, the impact of water droplets on heated surfaces with different roughness was studied using still and high speed photographic techniques and heat transfer measurements and the study encompassed droplet Weber numbers of 20, 60 and 220 and surface temperatures of 100-280°C.

Extraordinary shifts of the Leidenfrost temperature from multiscale micro/nanostructured surfaces.
Corey Kruse,Troy Anderson,Chris Wilson,Craig Zuhlke,Dennis R. Alexander,George Gogos,Sidy Ndao +6 more
TL;DR: Extraordinary shifts in the Leidenfrost temperatures were attributed to nanoporosity, reduction in contact angle, intermittent liquid/solid contacts, and capillary wicking actions resulting from the presence of self-assembled nanoparticles formed on the surfaces.

A numerical investigation of the evaporation process of a liquid droplet impinging onto a hot substrate
TL;DR: In this article, a numerical investigation of the evaporation process of n-heptane and water liquid droplets impinging onto a hot substrate is pre- sented, and the Navier-Stokes equations expressing the flow distribution of the liquid and gas phases, coupled with the Volume of Fluid Method (VOF) for tracking the liquid-gas interface, are solved numerically using the finite volume methodology.
