In this article, a novel method of increasing the dynamic Leidenfrosttemperature is proposed through the addition of both anionic (SDS) and cationic(CTAB) surfactants to water droplets. We focus on understanding thehydrodynamics and thermal aspects of droplet impact Leidenfrost behaviour ofsurfactant solutions, and aim to delay the onset of the Leidenfrost regime. Theeffects of Weber number (We), Ohnesorge number (Oh) and surfactantconcentration on dynamic Leidenfrost temperature were experimentally studied indetails, covering a wide gamut of governing parameters. At a fixed impactvelocity, increased with the increase of surfactant concentration. decreasedwith increase of impact velocity for all solutions of surfactant droplets at afixed surfactant concentration. We proposed a scaling relationship for in termsof We and Oh. At temperatures (~ 400oC) considerably higher than , dropletsexhibit trampoline like dynamics or central jet formation, associated withfragmentation, depending upon the impact velocity. Finally, a regime map of thedifferent boiling regimes such as transition boiling, Leidenfrost effect,trampolining and explosive behaviour is presented as function of impact We andsubstrate temperature (Ts). The findings may hold strong implications inthermal management systems operating at high temperatures
