Physical Modeling of Magma Melt Emissions with Its Degassing at Temperatures up to 2200°C in a Cold Crucible Induction Furnace

This article is devoted to the experimental study of bubbling of magma melt at temperatures up to 2200°C with melt emissions with the aim to physically simulate the process of volcanic eruption. To obtain the melt, the method of cold crucible induction melting (CCIM) of volcanic magma was used. A bottom bubbler was tested to conduct air bubbling of the melt. Parameters of the installation, design of its components, melting modes and conditions are presented. In addition, the release of melt during bubbling is shown. The results obtained during physical testing bring the conditions of physical modeling closer to the processes of volcanic eruptions and contribute to creation of more efficient installations for studying the processes of degassing and emissions of magma melts.
