Numerical simulations of volcanic jets: Importance of vent overpressure
[1] Explosive volcanic eruption columns are generally subdivided into a gas-thrust region and a convection-dominated plume. Where vents have greater than atmospheric pressure, the gas-thrust region is overpressured and develops a jet-like structure of standing shock waves. Using a pseudogas approximation for a mixture of tephra and gas, we numerically simulate the effects of shock waves on the ...
متن کاملUnsteady high‐pressure flow experiments with applications to explosive volcanic eruptions
[1] Motivated by the hypothesis that volcanic blasts can have supersonic regions, we investigate the role of unsteady flow in jets from a high‐pressure finite reservoir. We examine the processes for formation of far‐field features, such as Mach disk shocks, by using a shock tube facility and numerical experiments to investigate phenomena to previously unobtained pressure ratios of 250:1. The Ma...
متن کاملEffects of vent overpressure on buoyant eruption columns: Implications for plume stability
Volcanic plumes resulting from explosive volcanic eruptions present a variety of hazards depending on their behavior. Buoyant plumes heat and entrain enough of the surrounding air to rise high into the atmosphere, disrupting air traffic and causing regional ash fall. Alternatively, collapsed plumes produce dangerous fast-moving lateral flows of hot ash and gas. The transition between these beha...
متن کاملNumerical Determination of the Efficiency of Entrainment in Volcanic Eruption Columns
Entrainment of air by turbulent mixing plays a central role in the dynamics of eruption clouds; the amount of entrained air controls eruption styles and heights of eruption columns. The efficiency of entrainment is quantified by the entrainment coefficient: the ratio between mean inward radial velocity at the edge and the mean vertical velocity. We directly determined the entrainment coefficien...
متن کاملNumerical models of caldera-scale volcanic eruptions on Earth, venus, and Mars.
Volcanic eruptions of gassy magmas on Earth, Venus, and Mars produce plumes with markedly different fluid dynamics regimes. In large part the differences are caused by the differing atmospheric pressures and ratios of volcanic vent pressure to atmospheric pressure. For each of these planets, numerical simulations of an eruption of magma containing 4 weight percent gas were run on a workstation....
