Porous Media Tea Time Talk #7

We are happy to invite you to our next Porous Media Tea Time Talks (#PorousMediaTTT) session at 22.09.2020 at 15.00 pm CEST/local time on: https://www.youtube.com/channel/UCuK0ogQKdSxq6pW-vljLN1Q​.

 

This time we will be going from the modeling of filtration processes to the engineering challenges of a living porous medium! Remember that you can post questions anytime using the chat function on YouTube.

 

The two presentations are:

 

Filtration by porous media: combining microfluidics and stochastic modeling approach

By: Filippo Miele, CSIC Institute in Barcelona, Spain

 

  • I am investigating the role of flow disorder on filtration by heterogeneous porous media.
  • By means of microfluidics and time-lapse video microscopy I have access to both pore-scale dynamics and macroscopic data of Breakthrough Curves (BTC) and Retention Profiles (RP).
  • I developed a Continuous Time Random Walk model to predict BTC and RP from statistics of measured Lagrangia’s trajectories.

A Living Porous Media: Biology and Engineering of Termite Mound Construction

By: Saurabh Singh, Indian Institute of Science, Bangalore, India

 

  • Termite mounds are porous earthen structures built by termites for ventilation of their underground colonies. 
  • These mounds have a bi-layered architecture with a dense core that provides strength, and porous peripheries that facilitate regulated gaseous exchange. 
  • Termite make these mounds by depositing ‘bricks’ made by mixing moist soil with their secretions — the moisture imparts strength to the soil and the secretions impart weathering resistance.

 

The goal of the Porous Media TTT is to act as a complimentary platform to the already very successful Geoscience and Geoenergy webinars with the focus placed on young professionals.

 

This year is bringing in many new challenges to the worldwide porous media community, and those challenges can be particularly harsh against those of us at an early career stage. As conferences worldwide are being cancelled or postponed, many of us are found with little practical outlet to advertise our recent work and interact with the broader scientific community. With that in mind, we, a team of young porous media researchers from several different groups, have decided to create a virtual outlet, the Porous Media Tea Time Talks  to help fill in that gap in form of a regular webinar.

 

The 30 min webinar, including two presentations (2 x 10 + 5 min) from speakers of different institutes, will occur fortnightly at varying times to accommodate researchers from around the world.
