Testing Numerical Models of Glacier Flow

The Mechanics of Glacier Flow

The flow of valley glaciers is examined in the light of recent laboratory experiments on the behaviour of ice under load. Simple expressions are given for the velocity distributions in some cases of laminar flow, and the modification of a pure laminar flow theory necessary to explain the formation of transverse crevasses and thrust planes is considered. The paper ends with some remarks about th...

Subcooled two-phase flow boiling in a microchannel heat sink: comparison of conventional numerical models

Subcooled flow boiling in multi-microchannels can be used as an efficient thermal management approach in compact electrical devices. Highly subcooled flow boiling of HFE 7100 is studied in two microchannel heat sinks to choose a proper numerical model for simulating boiling flows in microchannels. Results of five different numerical models, including Volume of Fluid (VOF), Eulerian boiling, Eul...

Some Comments on Glacier Flow

Drs . O rowan and Perutz have shown that glacier ice does not behave as a viscous fluid but is plastic like all crystalline materials. The present authnr discusses two observed types of ice flow :-( 1) the normal, regular streaming flow in s low-moving glaciers; (2) Block-Sclzol/en" movement in swi ftl y flowing ice. Mention is made of the shear plane or laminar flow theory of Philipp. It appea...

Flow Laws for Glacier Ice: Comparison of Numerical Predictions and Field Measurements

Discussion has mainly focussed on the values of the rate various physical properties such as crystal size, ice fabric, and impurity content have been measured along the length of the core (Hammer and others, 1985; Herron and others, 1985). The bore hole itself has been studied for tilting and closure rates (Gundestrup and Hansen, 1984). In addition, there are three sets of ice-sounding radar su...
