Yu, G. (author), Tang, J. (author), Li, L. (author), Rossen, W.R. (author)The main objective of this study is to understand the vertical sweep efficiency with miscible CO2-water-coinjection as a secondary recovery method, from multiple perspectives: phase behavior, total relative mobility, fluid densities/viscosities, the driving forces and consequent phase distributions etc. We also seek to provide insights into...conference paper 2023

(author), Gogotsi, Yury (author)Achieving pseudocapacitive intercalation in MXenes with neutral aqueous electrolytes and driving reversible redox reactions is scientifically appealing and practically useful. Here, we report that the partial oxidation of MXene intensifies pseudocapacitive Li+ intercalation into Ti3C2Tx MXene from neutral water-in-salt electrolytes. An in...journal article 2022

Lyu, X. (author), Voskov, D.V. (author), Tang, J. (author), Rossen, W.R. (author)Foam injection is a promising enhanced-oil-recovery (EOR) technology that significantly improves the sweep efficiency of gas injection. Simulation of foam/oil displacement in reservoirs is an expensive process for conventional simulation because of the strongly nonlinear physics, such as multiphase flow and transport with oil/foam...journal article 2021

Tang, J. (author)Foam has unique microstructure in pore networks and reduces gas mobility significantly, which improves considerably the sweep efficiency of gas injection. Foam injection is thus regarded as a promising enhanced oil recovery (EOR) technology. One key to success of foam EOR is foam stability in presence of oil. This thesis seeks to understand...doctoral thesis 2019

Tang, J. (author), Ansari, Mohammed N. (author), Rossen, W.R. (author)The effectiveness of foam for mobility control in the presence of oil is key to foam enhanced oil recovery (EOR). A fundamental property of foam EOR is the existence of two steady-state flow regimes: the high-quality regime and the low-quality regime. Experimental studies have sought to understand the effect of oil on foam through its effect on...journal article 2019

Tang, J. (author), Vincent-Bonnieu, S.Y.F. (author), Rossen, W.R. (author)We present a CT coreflood study of foam flow with two representative oils: hexadecane C<sub>16</sub> (benign to foam) and a mixture of 80 wt% C<sub>16</sub> and 20 wt% oleic acid (OA) (very harmful to foam). The purpose is to understand the transient dynamics of foam, both generated in-situ and pre-generated, as a function of oil saturation...conference paper 2019

Tang, J. (author), Castañeda, Pablo (author), Marchesin, Dan (author), Rossen, W.R. (author)Understanding the interplay of foam and non-aqueous phases in porous media is key to improving the design of foam for enhanced oil recovery and remediation of aquifers and soils. A widely used implicit-texture foam model predicts phenomena analogous to cusp catastrophe theory: the surface describing foam apparent viscosity as a function of...journal article 2019

Tang, J. (author), Smit, Michiel (author), Vincent-Bonnieu, S.Y.F. (author), Rossen, W.R. (author)A new capillary number (N <sub>ca</sub> ) definition is proposed for 2-D etched micromodels. We derive the new definition from a force balance on a nonwetting ganglion trapped by capillarity. It incorporates the impact of pore microstructure on mobilization. The geometrical factors introduced can be estimated directly from image analysis of...journal article 2019

Tang, J. (author), Vincent-Bonnieu, S.Y.F. (author), Rossen, W.R. (author)Foam flow in porous media without oil shows two regimes depending on foam quality (gas fractional flow). Complexity and limited data on foam/oil interactions in porous media greatly restrict understanding of foam in contact with oil. Distinguishing which regimes are affected by oil is key to modeling the effect of oil on foam. We report...journal article 2019

Tang, J. (author), Vincent-Bonnieu, S.Y.F. (author), Rossen, W.R. (author)We present a CT coreflood study of foam, both pre-generated and generated in-situ, displacing oil, as a function of oil type and saturation. Foam generation and propagation are reflected through sectional pressure measurements. Dual-energy CT imaging monitors in-time phase saturations. With an oil less harmful to foam (hexadecane), injection...journal article 2019

Tang, J. (author), Avallone, F. (author), Bontempo, R. (author), van Bussel, G.J.W. (author), Manna, M. (author)This paper reports an experimental investigation on the effect of the duct geometry on the aerodynamic performance of an aerofoil shaped ducted wind turbine (DWT). The tested two-dimensional model is composed of an aerofoil equipped with pressure taps and a uniform porous screen. The experimental setup is based on the assumption that the duct...journal article 2018

Tang, J. (author), van Bussel, G.J.W. (author)A new high-lift aerofoil modification for the duct has been developed and will be experimentally tested in a small wind tunnel. Aerofoils for such wind tunnel ducts typically operate in the low Reynolds number range from 2 × 105 to 6 × 105. The effect of a duct and of rotor on power and pressure drop were considered separately in previous...abstract 2017

A screen mesh is used to simulate the energy extraction mechanisms of a wind turbine in experiment. Different screen porosities corresponding to different turbine loading coefficients are tested. Measurements of the axial force and of the velocity...journal article 2016

(author)Steel is prone to corrosion induced by chloride ions, which is a serious threat to reinforced concrete structures, especially in marine environments. In this work, we report a novel capsule-based selfrecovery system that utilizes chloride ions as a trigger. These capsules, which are functionalized via a smart response to chloride ions, are...journal article 2015

Tang, J. (author)Variable-stiffness panels have previously shown enhanced buckling performance compared to constant-stiffness panels, due to the beneficial load and stiffness redistribution. Two semianalytical models based on the Galerkin method and the Ritz method have been developed in order to solve the buckling problem of variable-stiffness composite panels ...master thesis 2015
