Estimating nonlinearities in twophase flow in porous media

In order to analyze numerically inverse problems several techniques based on linear and nonlinear stability analysis are presented. These techniques are illustrated on the problem of estimating mobilities and capillary pressure in one-dimensional two-phase displacements in porous media that are performed in laboratories. This is an example of the problem of estimating nonlinear coefficients in ...

High Speed Photograpic Observation of Flow Patterns during Flow Boiling in Single Rectangular Minichannel

The present study extends the range of flow patterns observed during boiling of water in a single minichannel of height 197 μm and width 1054 μm. The calculated hydraulic diameter of the channel is 333 μm. High-speed photography is used to obtain video images of the flow field. The top covers of the channels are made of Lexan to permit visual observation, while the minichannel is machined in a ...

Detection of Two-phase Flow Patterns in a Vertical Minichannel Using the Recurrence Quantification Analysis

The two-phase flow (water-air) occurring in square minichannel (3x3 mm) has been analysed. In the minichannel it has been observed: bubbly flow, flow of confined bubbles, flow of elongated bubbles, slug flow and semi-annular flow. The time series recorded by laser-phototransistor sensor was analysed using the recurrence quantification analysis. The two coefficients:Recurrence rate (RR) and Dete...
