Exact solution of viscous-plastic flow equations for Glacier dynamics in 2-dimensional case
Here is presented a new exact solution of Ice dynamics in Glaciers in terms of viscousplastic theory of movements, for 2-dimensional case. In general case, 2-D solution of Ice dynamics could be classified as Riccati’s type. Due to a very special character of Riccati’s type equation, it’s general solution is proved to have a proper gap of components of such a solution. It means a possibility of ...
متن کاملThe 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...
متن کاملViscous Fluid Flow-Induced Nonlocal Nonlinear Vibration of Embedded DWBNNTs
In this article, electro-thermo nonlocal nonlinear vibration and instability of viscous-fluid-conveying double–walled boron nitride nanotubes (DWBNNTs) embedded on Pasternak foundation are investigated. The DWBNNT is simulated as a Timoshenko beam (TB) which includes rotary inertia and transverse shear deformation in the formulation. Considering electro-mechanical coupling, the nonlinear govern...
متن کاملA model of glottal flow incorporating viscous-inviscid interaction
A model of flow passing through the glottis is presented by employing the boundary-layer assumption. A thin boundary layer near the glottal wall influences the flow behavior in terms of the flow separation, jet formation, and pressure distribution along the channel. The integral momentum relation has been developed to analyze the boundary layer accurately, and it can be solved numerically for t...
متن کاملSome 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...
