These are characterised by heat and mass transfer processes, such as evaporation, condensation and boiling. However, studies regarding droplets and liquid films under non-isothermal conditions are scarce in the literature and do not explore temperature-dependent phenomena. Due to this, the main objective of this work is to evaluate the influence of temperature on the splashing occurrence of single droplets impinging onto liquid films under the presence of a heat flux. The crown evolution is evaluated qualitatively to provide insight regarding breakup mechanisms. Water, n-heptane and n-decane are the fluids considered for the current study, as these provide a wide range of thermophysical properties and saturation temperatures. The splashing dynamics are evaluated by varying the droplet impact velocity and dimensionless temperature of the liquid film. Qualitative results show that an increase in the liquid film temperature leads to the transition from spreading to splashing, which is less evident for fuels in comparison with water. For water and n-heptane, the formation of cusps on the crown rim is promoted, which is associated with ligament breakup. For n-decane, the crown rims are relatively homogeneous in terms of shape and size, whereas the atomisation process varies a function of the liquid film temperature. Visually, the secondary droplets exhibit a greater size in comparison with lower temperatures. Transitional regimes display some irregularities, such as splashing suppression\/reduction, which require further attention. In terms of splashing correlation, the authors propose to develop a non-splash\/splash boundary for both iso- and non-isothermal conditions. Results show that the splashing threshold is dependent on the thermophysical properties and the dimensionless temperature of the liquid film.<\/jats:p>","DOI":"10.1007\/s00348-024-03942-6","type":"journal-article","created":{"date-parts":[[2025,2,7]],"date-time":"2025-02-07T15:22:20Z","timestamp":1738941740000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Splashing correlation for single droplets impacting liquid films under non-isothermal conditions"],"prefix":"10.1007","volume":"66","author":[{"given":"Daniel","family":"Vasconcelos","sequence":"first","affiliation":[]},{"given":"Jorge","family":"Barata","sequence":"additional","affiliation":[]},{"given":"Andr\u00e9","family":"Silva","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2025,2,7]]},"reference":[{"key":"3942_CR1","doi-asserted-by":"publisher","DOI":"10.4271\/950283","author":"C Bai","year":"1995","unstructured":"Bai C, Gosman A (1995) Development of methodology for spray impingement simulation.
