Description

Boiling is among the heat transfer mechanisms commonly used in practical applications. The theoretical description of boiling relies on numerous factors: the influence of chemical and physical surface properties, system pressure and the effects of the temporal and spatial scales. These features have made experimental studies of boiling processes rather complicated, resulting sometimes in different interpretations the research findings. At present, most investigations of boiling processes, including those carried out using modern experimental high-speed techniques including infrared thermography, laser interferometry etc, are mostly conducted at atmospheric pressure with limited research on the effects of subatmospheric pressures. Due to the increasing demand for subatmospheric pressure applications, knowledge on the effects of pressure reducing on the multiscale boiling characteristics is highly desirable.
