In this paper, the mechanism of fault pressurization in rapid slip events is analyzed on the basis of a complete characterization of the thermo-poro-mechanical behavior of a clayey gouge extracted at 760m depth in Aigion fault in the active seismic zone of the Gulf of Corinth, Greece. It is shown that the thermally collapsible character of this clayey gouge can be responsible for a dramatic red...

Therapeutic ultrasound is widely employed in clinical applications but its mechanism of action remains unclear. Here we report prompt fluidization of a cell and dramatic acceleration of its remodeling dynamics when exposed to low intensity ultrasound. These physical changes are caused by very small strains (10-5) at ultrasonic frequencies (106 Hz), but are closely analogous to those caused by r...

Fischer-Tropsch synthesis is one of the most important catalytic reactions that convert the synthetic gas to light and heavy hydrocarbons. One of the main issues is selecting the type of reactor. The slurry bubble reactor is suitable choice for FischerTropsch synthesis because of its good qualification to transfer heat and mass, high durability of catalyst, low cost maintenance and repair. The ...

In this study, a mathematical model of hydrogen production from glycerol gasification in supercritical water was established based on the CFD-DEM method. The fluidization process fluidized bed and effects height feed structure particle distribution residence time feedstock were analyzed. Additionally, temperature field bed, reaction rate each influence wall gas yields also studied. simulation r...

Hydrogen-based direct reduced iron (HyDRI) produced by fluidized bed has great potential for achieving the target of net-zero carbon in steelmaking. However, when magnetite ores were used as feedstock, several process parameters showed influences on its fluidization and reduction behaviors. To confirm dominant influencing factors optimum condition, orthogonal experimental method was conducted p...

Direct reduction of combusted iron powders using renewable energy is one the keys to ensure a carbon-neutral fuel cycle. Based on (de-)fluidization experimental study in Part I, experiments micron-sized hydrogen lab-scale gas-fluidized bed are conducted at temperatures ranging from 500 ∘C 650 ∘C. The effects temperature, velocity and concentration performance (including degree, particle morphol...

The processes of dehydration and granulation are associated with the heat transfer to solid particles from gas coolant, which acts as a fluidizing agent causes stochastic movement granular material in apparatus. To implement layered structure mechanism organic-mineral fertilizers it is necessary ensure intensive circulation gradual passage through appropriate technological zones main problem lo...
