ABSTRACT WALDBAUM1 has suggested that, when mantle material convects according to the model of Turcotte and Oxburgh2, the temperature of an isolated rising mass will increase, “even in the

idealized case where friction, viscosity and turbulence are ignored”. He argues from the premise that the steady adiabatic flow of a fluid is isenthalpic along streamlines: the Joule–Kelvin

coefficient of the fluid can therefore be used to predict the temperature change during decompression. Access through your institution Buy or subscribe This is a preview of subscription
