Cooling of a channeled lava flow with non-Newtonian rheology: crust formation and surface radiance
Rheology Magmas Thermodynamics Lava flow Effusion rate
2015/8/27
We present here the results from dynamical and thermal models that describe a channeled lava flow as it cools by radiation. In particular, the effects of power-law rheology and of the presence of bend...

Dilatant non-Newtonian fluids similarity solution nonlinear boundary value problem
2011/10/13
A rigorous proof of existence and uniqueness of solutions to a singular nonlinear boundary value problem in the theory of Dilatant non-Newtonian fluids is given and a theoretical estimate formula for ...
Dynamics of stochastic non-Newtonian fluids driven by fractional Brownian motion with Hurst parameter $H \in (1/4,1/2)$
fractional Brownian motion stochastic non-Newtonian fluid random attractor

Abstract: In this paper we consider the Stochastic isothermal, nonlinear, incompressible bipolar viscous fluids driven by a genuine cylindrical fractional Bronwnian motion with Hurst parameter $H \in ...
Influence of Non-Newtonian rheology on magma degassing
Non-Newtonian rheology magma degassing Soft Condensed Matter
2011/8/4
Abstract: Many volcanoes exhibit temporal changes in their degassing process, from rapid gas puffing to lava fountaining and long-lasting quiescent passive degassing periods. This range of behaviors h...
Accurate Measurement in the Field of the Earth of the General-Relativistic Precession of the LAGEOS II Pericenter and New Constraints on Non-Newtonian Gravity
General-Relativistic Pericenter Constraints on Non-Newtonian Gravity
2011/9/14
The pericenter shift of a binary system represents a suitable observable to test for possible deviations from the Newtonian inverse–square law in favor of new weak interactions between macroscopic obj...
Pore-Scale Modeling of Non-Newtonian Flow in Porous Media
Pore-Scale Modeling Non-Newtonian Flow Porous Media
2010/11/12
The thesis investigates the flow of non-Newtonian fluids in porous media using pore-scale network modeling. Non-Newtonian fluids show very complex time and strain dependent behavior and may have initi...
Controllability of non-Newtonian fluids under homogeneous extensional flow
Controllability of non-Newtonian fluids homogeneous extensional flow
2010/9/14
In the discipline of non-Newtonian materials, the ability to control viscoelastic stresses is very desirable in ascertaining important properties of the influenced materials. We apply the nonlinear ge...
Rotating Disk Flow With Heat Transfer of a Non Newtonian Fluid in Porous Medium
Rotating disk flow Heat Transfer Porous medium Non-Newtonian fluid
2010/4/9
The steady flow of an incompressible viscous non-Newtonian fluid above an infinite rotating disk in a porous medium is studied with heat transfer. Numerical solutions of the nonlinear differential equ...
