1火山通道岩浆流动动力学模型在天池火山喷发过程中的应用显示文摘在圆柱形火山通道的下部,岩浆上升速度与岩浆粘度、密度及压力有关。这时的流体动力学过程可以应用一般的牛顿流体模型。火山通道中部气泡化岩浆上升时,液相和气相的转化符合质量守恒方程,混合相总体符合动量守恒方程。其中气泡形成与生长过程符合达西定律与数密度方程。在火山通道靠上部的碎屑化带里,不同组分符合质量守恒方程,混合相总体符合动量守恒方程。天池火山千年大喷发时,通道直径是62m。岩浆房内的岩浆含有约3%体积百分数的气泡,气泡体积在65%时岩浆破碎,颗粒离开通道时的速度是145ms^(-1),而气体离开通道时的速度是170ms^(-1)。气体颗粒分散相出口压力是12.2MPa。在破火山口塌陷之前,岩浆房内气泡体积可高达30%~40%。与此同时,碎屑化发生时岩浆的孔隙度也增加到70%~75%左右。这时的出口压力降低至7~8MPa,出口气体速度增加到180ms^(-1)。气象站碱流质寄生火山喷发对应的喷发通道直径是40m,喷发以气体出口速度15~25ms^(-1)的弱爆破性喷发和侵出式喷发为特征。这时浮岩的孔隙度比千年大喷发的孔隙度低,为48%~61%,而浮岩密度高,为1.01~1.35gcm^(-3)。在侵出相喷发时最高释放率可以达到42m^3s^(-1)(致密岩石当量 DRE),孔隙度变化范围是70%~80%。魏海泉 Melnik O 刘永顺 Barmin A Sparks RSJ 2006岩石学报2006,22,12:2
