Description

A major effort in evaluating Kilauea Iki lava lake has been completed. The physical model based on FY 76 geophysical experiments is not correct in that a low viscosity, liquid lens of appreciable thickness does not exist. Mathematical models of the cooling of the lava lake and the state of solidification of the liquid lens were verified by thermal profile and permeability measurements. New jet-augmented drilling concepts successfully penetrated the viscous, multi-phase molten rock region in some locations where conventional drilling failed. Heat transfer studies in the lake suggest injection of fluids to enhance convection may be useful to extract ... continued below

Description

A major effort in evaluating Kilauea Iki lava lake has been completed. The physical model based on FY 76 geophysical experiments is not correct in that a low viscosity, liquid lens of appreciable thickness does not exist. Mathematical models of the cooling of the lava lake and the state of solidification of the liquid lens were verified by thermal profile and permeability measurements. New jet-augmented drilling concepts successfully penetrated the viscous, multi-phase molten rock region in some locations where conventional drilling failed. Heat transfer studies in the lake suggest injection of fluids to enhance convection may be useful to extract energy from magma chamber margins. Other activities resulted in the completion and successful testing of a 800 cc simulation facility for evaluating simulated magma properties at temperatures to 1500/sup 0/C and pressures to 4 kbar. In materials compatibility studies, thermodynamic stability diagrams were developed for 15 pure metals in basaltic magma systems and compatibility tests completed. Results are being used to define simple alloy systems which may be compatible with magmas and to identify other superalloy materials candidates.
