527. Ultrasonic Study of Water Adsorbed in Nanoporous Glasses

Gennady Gor (New Jersey Institute of Technology)

25/05/2023, 09:15

(MS23) Special Session in honor of Signe Kjelstrup

Oral Presentation

Thermodynamic properties of fluids confined to nanopores differ from those observed in the bulk. To investigate the effect of nanoconfinement on compressibility of water, we measured water adsorption isotherm concurrently with compressional and shear ultrasonic velocities for two nanoporous glass samples. These measurements yield the longitudinal and shear moduli of the water-saturated...

1009. A (dual) network model for heat transfer in coupled porous media free flow systems

Rainer Helmig (University of Stuttgart)

25/05/2023, 09:30

(MS23) Special Session in honor of Signe Kjelstrup

Oral Presentation

Heat transfer processes and non-isothermal effects are found in many technical and environmental coupled porous-media free flow systems.
Prominent examples including two-phase flow range from fuel-cell water management
and food drying to soil evaporation and salinization. Modeling these types of systems is challenging due to the variety of length and time scales involved and the high...

1008. Colloidal particles adsorption fluctuations: experimental and kirkwood buff integrals approaches

Jean-Marc Simon (Université de Bourgogn)

25/05/2023, 09:45

(MS23) Special Session in honor of Signe Kjelstrup

Oral Presentation

Colloidal particles (amidine latex, 1 μm in diameter) in aqueous solution are put in contact with a glass slide under ambient conditions where they adsorb. The particle concentration is fixed during the experiment by mean of an infinite reservoir. Using a simple optical microscope, 240 x 320 μm2 images of the population of the adsorbed particles are taken while the glass slide and the solution...

645. Local Equilibrium in Liquid Phase Shock Waves

Tage W. Maltby (NTNU)

25/05/2023, 10:00

(MS23) Special Session in honor of Signe Kjelstrup

Oral Presentation

Porous media can experience shock waves under certain conditions, for instance under ultrasound exposure [1]. Shock waves are also observed in typical Hele-Shaw cells, during Haines jumps [2]. Modelling this is a vital part for understanding these complex phenomena. The question therefore arises; is it possible to use the governing equations for systems without shock waves; the balance laws...

251. Comparison of two optimization approaches in an electrochemical reaction-diffusion system from an entropy generation perspective

Mr Mehrzad Alizadeh (Department of Mechanical Engineering, Graduate School of Engineering, Osaka University, Suita, 565-0871, Osaka, Japan)

25/05/2023, 14:00

(MS23) Special Session in honor of Signe Kjelstrup

Oral Presentation

As the use of electrochemical energy devices, such as rechargeable batteries and fuel cells increases in many fields, from stationary power generation to transportation and heavy-duty applications, it is imperative to further improve them to make them cost-effective compared to conventional systems [1]. The search for the best composition for porous electrodes of these technologies has been...

885. Is salt precipitation an issue during geological storage of hydrogen in saline aquifers? from thermodynamic perspective using PC-SAFT EoS

Mohammad Masoudi (University of Oslo, Department of Geosciences)

25/05/2023, 14:15

(MS23) Special Session in honor of Signe Kjelstrup

Oral Presentation

During the Underground Hydrogen Storage (UHS) process, hydrogen gas must be transported from the production site to the storage site, be injected into the storage repository (depleted hydrocarbon reservoir, aquifer, or salt cavern), and finally the stored hydrogen needs to be released from the storage site and be transported to the distribution points. During this long journey, hydrogen...

1023. Ion adsorption at nanoscale interfaces out of equilibrium

Fernando Bresme (Imperial College)

25/05/2023, 14:30

(MS23) Special Session in honor of Signe Kjelstrup

Oral Presentation

Liquids under nanoconfinement and non-equilibrium conditions feature in many problems of interest in energy recovery, management of energy dissipation or liquid storage. Nanoconfinement influences the structure of liquids and their response to external fields. In this talk, I will discuss recent investigations, using non-equilibrium molecular dynamics techniques, on the coupling effects...

532. The role of Stern layer ions in ionic transport in porous media

Claire Chassagne (TU Delft)

25/05/2023, 14:45

(MS23) Special Session in honor of Signe Kjelstrup

Oral Presentation

Understanding the role of Stern layer ions is crucial for assessing the ionic transport in nanochannels at high ionic strengths. Currently, MD simulations are one of the most promising tools to offer a realistic picture of the ionic behaviour close to charged surfaces where the Stern layer is located [1,2]. Experiments (like streaming potential and titration), on the other hand, are modelled...

1020. Dynamic contact angles and dynamic regimes for advancing liquid fronts

Prof. Ignacio Pagonabarraga (University of Barcelona)

25/05/2023, 15:00

(MS23) Special Session in honor of Signe Kjelstrup

Oral Presentation

Flocks of birds, schools of fishes, or bacterial colonies constitute examples of living systems that coordinate their motion. In all these systems their constituent elements generate motion due to energy consumption and can exchange information or react sensitively to chemical cues in order to move together or to react collectively to external signals. Artificial systems, such as Janus...
