Description

Technical Field

[0001] The invention relates to the technical field of teaching equipment, and in particular to a pyroclastic deposition simulation device and method. Background Art

[0002] A volcano is a landform formed by volcanic eruptions and composed of lava and volcanic debris. Usually, the volcano is cone-shaped and mainly consists of a volcanic cone, a crater and an vent. There are above-water volcanoes and underwater volcanoes. When teaching, students are generally shown the situation of a volcanic eruption through simulation. The traditional volcanic eruption simulation device is set in a transparent box, and then a device simulating a volcanic eruption is placed in the box for simulation operation. Then the debris deposition produced by the simulated volcanic eruption is observed and measured in sequence. After the volcanic eruption simulation is completed, the deposition thickness of debris and dust of different particle sizes at different distances from the vent is measured in sequence. There is a large workload and it is somewhat cumbersome. At the same time, since students need to observe at a certain distance during the demonstration, and the observation angle is relatively fixed, it will also affect the teaching effect.
