Viscous Dissipation | John Seach
Thermal instability in volcanic conduits may lead to explosive eruptions due to viscous dissipation.
Forced Intrusion Model
Calculations of energy balance on a forced intrusion magma flow make it possible to determine the critical conduit size below which magma will solidify.
Viscous Dissipation and Thermal Runaway
In 1974 Fuji and Uyeda showed that thermal runaway occurs when the ratio of viscous dissipation to conduction effects exceeds a critical value of about 5.5.
