Dynamics of fluid and heat flow in a CO2-based injection-production geothermal system
Binary system CO2-water displacement Heterogeneity Preferential flow
2018/3/23
CO2 is now considered as a novel heat transmission fluid to extract geothermal energy. It can be used for both energy exploitation and CO2 geological sequestration. Here, a 3-D, “two-spot” pattern wel...
Numerical simulation of explosive volcanic eruptions from the conduit flow to global atmospheric scales
numerical modeling explosive volcanic eruptions conduit flow multiphase flow simulation stratospheric sulfate aerosol
2015/9/10
Volcanic eruptions are unsteady multiphase phenomena, which encompass many inter-related processes across the
whole range of scales from molecular and microscopic to macroscopic, synoptic and global....
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...
Optical method for measuring bed topography and flow depth in an experimental flume
Optical method bed topography flow depth experimental flume
2014/12/31
We describe an optical method known as moiré for acquiring quasi-simultaneous measurements of bed topography and flow depth in laboratory experiments. The moiré method is based on projecting a fringe ...

This paper presents the Contrast Invariant and Affine Optical Flow(CIAO), a dense area-based sub-pixel image matching algorithm.CIAO does not force the estimated disparity field between two images to ...
Was the magnitude (M = 9.0R) of the mega-earthquake of Japan (11th of March, 2011) predictable? An analysis based on the Lithospheric Seismic Energy Flow Model (LSEFM)
Tohoku earthquake earthquake magnitude lithosphere cumulative seismic energy mega-earthquakes seismic potential maps
2012/4/20
The Tohoku EQ (11th of March, 2011, M = 9.0) in Japan falsified the proposed EQ magnitude range (M = 7.0 - 8.5) of the same seismogenic regional area that had been determined by the compiled hazard ma...

A risk reduction program was developed after debris-flow disaster analysis is conducted using mitigation structures, evacuation measures and community restrained expansion strategy. The risk assessmen...
Baroclinic instability of a symmetric,rotating,stratified flow:a study of the nonlinear stabilisation mechanisms in the presence of viscosity
Baroclinic instability nonlinear stabilisation mechanisms presence of viscosity
2009/11/12
This paper presents the analysis of symmetric circulations of a rotating baroclinic flow, forced by a steady thermal wind and dissipated by Laplacian friction. The analysis is performed with numerical...
Flow partitioning and unstable divergence in fluviokarst evolution in central Kentucky
Flow partitioning unstable divergence fluviokarst evolution central Kentucky
