TL;DR: In this paper, an extensive literature review conducted within Edinburgh University's Fire Safety Engineering Group and sponsored by the UK Home Office Fire Research and Development Group was conducted to establish the current state-of-the-art regarding the use of water sprays for the suppression and extinguishment of typical (Class ‘A) compartment fires and to identify where gaps exist in the current knowledge.

TL;DR: In this article, a linear stability theory for small perturbations of straight free liquid jets moving in air is presented, and an estimate of the main droplet size emerging from capillary breakup is provided.
Abstract: This chapter deals with capillary instability of straight free liquid jets moving in air. It begins with linear stability theory for small perturbations of Newtonian liquid jets and discusses the unstable modes, characteristic growth rates, temporal and spatial instabilities and their underlying physical mechanisms. The linear theory also provides an estimate of the main droplet size emerging from capillary breakup. Formation of satellite modes is treated in the framework of either asymptotic methods or direct numerical simulations. Then, such additional effects like thermocapillarity, or swirl are taken into account. In addition, quasi-one-dimensional approach for description of capillary breakup is introduced and illustrated in detail for Newtonian and rheologically complex liquid jets (pseudoplastic, dilatant, and viscoelastic polymeric liquids).

TL;DR: In this paper, the authors report on increasing the Leidenfrost temperature by surface textures that can promote droplet wetting at high superheat via capillary wicking, which is undesirable in cooling applications as the vapor layer on which the liquid levitates acts as a heat transfer barrier.
Abstract: The Leidenfrost effect is undesirable in cooling applications as the vapor layer on which the liquid levitates acts as a heat transfer barrier. Here, we report on increasing the Leidenfrost temperature by surface textures that can promote droplet wetting at high superheat via capillary wicking. Counterintuitively, we find that sparser rather than denser textures increase the Leidenfrost temperature. Our experimental results are consistent with a physical model that balances capillary wetting pressures with dewetting pressures exerted by the escaping vapor. The physical mechanism suggests that hierarchical textures have a higher Leidenfrost temperature compared to single-length-scale textures, which is confirmed experimentally.
