Abstract:During the quenching of high‐temperature steel plate, Leidenfrost phenomenon takes place, which prevents the coolant from extracting heat from high‐temperature wall. Adding surfactant to the basic fluid can reduce the surface tension, increase the solid–liquid contact area, and ultimately increase the cooling speed. Herein, aqueous solutions of 240 ppm cetyl trimethyl ammonium bromide (CTAB), 600 ppm sodium dodecyl sulfate (SDS), and 56 ppm polyoxyethy‐lene (20) sorbaitan monolaurate (Tween‐20) are used as coo… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
