Two-phase flow regimes are affected by conduit position, alignment, geometry, flow direction, physical characteristics, and flow rate of each phase as well as the heat flux toward the boundaries. Due to the importance of two-phase flow, numerous regimes have been identified. The first step in studying micro-bubble formation inside a venturi tube is to recognize the type of flow regimes. In this...

We present a reactive multi-component multi-phase flow program for simulating Geological Carbon Sequestration (GCS), an approach that reduces carbon emissions by storing CO2 in deep subsurface formations. The program, called MRST_CO2, is implemented the library Matlab Reservoir Simulation Toolbox (MRST). It can simulate and transport of species undergoing chemical reactions mass exchanges among...

Experiments of unstable vapor liquid two phase flow phenomena during boiling with HFE-7100 in parallel rectangular multi-microchannels aspect ratios 0.2364 and 0.3182 were conducted under a wide range test conditions: the mass flux from 380 to 3500 kg/m2s, heat 0 1080 kW/m2 compressive volumes 0, 5, 10 20 ml, respectively. First, characteristics transfer two-phase pressure drop are compared eac...

Multi-phase flows are one of the challenges on which the CFD simulation community has been working extensively with a relatively low success. The phenomena associated behind the momentum and heat transfer mechanisms associated to multi-phase flows are highly complex requiring resolving simultaneously for multiple scales on time and space. Part of the reasons behind the low predictive capability...

The phase-field method is reviewed against its historical and theoretical background. Starting from Van der Waals considerations on the structure of interfaces in materials the concept of the phase-field method is developed along historical lines. Basic relations are summarized in a comprehensive way. Special emphasis is given to the multi-phase-field method with extension to elastic interactio...

in our search for new anticancer medicinal plants, the antiproliferative activity of the methanol extract of daphne mucronata (thymelaeaceae) was evaluated using human myelogenous leukemia k562 cells. the cells responded to plant treatments in a dose dependent manner and the ic50 of the crude extract (equivalent to 1 g of plant leaves powder per ml) and the purified active component were found ...
