Erosion: Thermal, Lava Flows, Modeling

Scientific paper

Lavas are hypothesized to carve channels by thermal erosion. This study models thermal erosion using Polyethylene Glycol (PEG) as an analog for lavas. PEG has been used in a variety of studies to model lava flows. Two previously formulated melt rate equations are compared to the measured erosion rates. Neither equation was found to match the experimental results equation 1 was 2 orders of magnitude too low and equation 2 was 80-90% too high. This is probably because the theoretical equations do not account for decreased heat transfer at the base of the flow.
