Abstract

Convective heat flow measurements of a basaltic lava flow were made during the 1983 eruption of Kilauea volcano in Hawaii. Eight field measurements of induced natural convection were made, giving heat flux values that ranged from 1.78 to 8.09 kilowatts per square meter at lava temperatures of 1088 and 1128 degrees Celsius, respectively. These field measurements of convective heat flux at subliquidus temperatures agree with previous laboratory measurements in furnace-melted samples of molten lava, and are useful for predicting heat transfer in magma bodies and for estimating heat extraction rates for magma energy.

摘要

对流热流测量玄武岩熔岩流在 1983 年夏威夷基拉韦厄火山喷发期间进行。进行了 8 次诱导自然对流的现场测量，在熔岩温度分别为 1088 和 1128 摄氏度的情况下，得到的热通量值分别为 1.78 至 8.09 千瓦/平方米。这些亚液态温度下的对流热通量的现场测量结果与以前在熔融熔岩炉熔样品中的实验室测量结果一致，对于预测岩浆体中的热传递和估算岩浆能量的热提取速率很有用。
