Record #126416:

A computationally feasible reduction of the O'Neill--Miller model of secondary frost heave / Andrew C. Fowler, C.G. Noon, W.B. Krantz.

Title: A computationally feasible reduction of the O'Neill--Miller model of secondary frost heave / Andrew C. Fowler, C.G. Noon, W.B. Krantz.
Author(s): Fowler, Andrew C.
Noon, C. G.
Krantz, W. B.
Date: 1993.
Publisher: Wushan, Guangzhou: South China University of Technology Press
In: Permafrost. Sixth International Conference. Proceedings (Vol. 2), July 5-9, 1993, Beijing China. (1993.),
Abstract: Asymptotic reduction of this model yields quantitatively accurate representation of original model, but involves only solution of two first-order ordinary differential equations. Reduction is made on basis that frozen fringe is thin, conduction of heat dominates advection of heat, and permeability of frozen fringe is strongly sensitive to water content. Solutions give predictions of heave versus time and of time of formation and thickness of discrete ice lenses, which agree with O'Neill and Miller's numerical results.
