Revisiting Glacier Dynamics for Stationary Approximation of Plane-Parallel Creeping Flow

نویسندگان

چکیده

We have presented in this analytical research the revisiting of approach for mathematical modeling Glacier dynamics terms viscous-plastic theory 2-dimensional movements within (x, y)-plane cartesian coordinates. The stationary creeping approximation plane-parallel flow slowly moving glacial ice on absolutely flat surface without any inclination has been considered. Even such simple formulation, equations motion that governs by is hard to be solved analytically. succeeded obtaining expression components velocity Ox-direction (Ox-axis coincides initial main direction ice). Restrictions form stem from continuity equation as well special condition non-Newtonian (viscous-plastic) used insofar.

Flow dynamics of Byrd Glacier, East Antarctica

Force-balance calculations on Byrd Glacier, East Antarctica, reveal large spatial variations in the along-flow component of driving stress with corresponding sticky spots that are stationary over time. On the large scale, flow resistance is partitioned between basal (�80%) and lateral (�20%) drag. Ice flow is due mostly to basal sliding and concentrated vertical shear in the basal ice layers, i...

Modified Linear Approximation for Assessment of Rigid Block Dynamics

This study proposes a new linear approximation for solving the dynamic response equations of a rocking rigid block. Linearization assumptions which have already been used by Hounser and other researchers cannot be valid for all rocking blocks with various slenderness ratios and dimensions; hence, developing new methods which can result in better approximation of governing equations while keepin...

Creeping motion in granular flow.

The core of a quasi-two-dimensional rotating cylinder filled more than half full with glass beads rotates slightly faster than the cylinder itself and decreases in radius over time. Core precession depends linearly on the number of tumbler revolutions while core erosion varies logarithmically. Both processes serve to quantify the slow granular motion in the "fixed" bed and depend on the filling...

Numerical Study of Interaction of Two Plane Parallel Jets

In the present work, a numerical simulation of two parallel turbulent jets was performed. The simulations were carried out by using the  standard, the  standard and the RSM models. A parametric study was also presented to determine the effect of the nozzles spacing and velocity ratio on the axial and transverse positions of the merge and combined points. Correlations between the various paramet...
