TL;DR: In this paper, a method for measuring the Sherwood number between a gas and a liquid in a porous medium by applying CT (Computed Tomography) was proposed, which comprises a CT scanning system and a gas-liquid mass transfer system.

TL;DR: In this paper, a method for calculating an empirical relation expression between gas-liquid Sherwood numbers inside a porous medium by applying CT is proposed, which comprises the steps of firstly calculating the bubble volume content and a gas- liquid mass transfer Sherwood number inside the porous medium of different gas injection and liquid injection directions according to a CT image stack; calculating a liquid-phase Reynolds number according to lamellar average porosity, the bubble volumetric content and the liquid injection speed; classifying the acquired sherwood numbers, the Reynolds numbers and the volume content values into

TL;DR: In this article, a method for measuring area changes of CO2-saline water interfaces in a porous medium by using a CT was proposed, which comprises the steps of firstly preparing saline water containing potassium iodide to strengthen the image contrast of CO 2-salinity water; continuously scanning by using the CT to obtain unsteady-state porous medium images under the CO 2saturated condition and different injection conditions; removing a noisy point by using filter and carrying out threshold processing to generate binary images only containing 0 and 1 of saturated CO2; carrying out subtraction on

TL;DR: In this paper, an improved vertical Hele-Shaw box and a two-phase fluid density difference convective mixing experimental system formed by the improved vertical type Hele Shaw box is described.
