Is it possible to bridge molecular-scale processes with macroscopic models to better understand wetting dynamics on hydrophilic surfaces? This intriguing question is addressed in the thesis “Bridging the Molecular and the Continuous Pictures of Wetting Dynamics on Hydrophilic Surfaces.” by Michele Pellegrino. The study includes parameterizing continuous fluid dynamics models, like Phase Field and Volume of Fluid, to enhance their accuracy.

Michele’s main supervisor was Professor Berk Hess. His co-advisor was Shervin Bagheri.

It has been a lot of fun to have you in the FSG group over the last 5 years Michele, and best of luck in the future career!

We are happy that Seyed Morteza Habibi Khorasani defended his PhD thesis entitled “Turbulent flows over permissive boundaries and porous walls” in April 12. The discussion with Profs. Alfredo Soldati, Ricardo Garcia Mayoral and Angle Busse were both intense and enjoyable.

Seyed’s thesis is entitled “Turbulent flows over permissive boundaries and porous walls” and can be downloaded here.

Congratulations Seyed!

We are super excited to host the sabbatical ofProf. Ian Jacobi from Department of Aerospace Engineerning, Technion. Ian received his MS (2008) and PhD (2012) in Aeronautical Engineering from Caltech, for experimental work in turbulent boundary layers. From 2012-2014, served as a post-doctoral research fellow at Princeton University, conducting experiments on microfluidic technologies for drag reduction and flow control. He joined the Technion in 2014. Welcome!

Julien is the latest member of the group!

“I was born in Voghera, Italy, in 1998. I studied aeronautical engineering at Politecnico di Milano obtaining a bachelor’s degree in 2019 and a master’s degree in 2023. During my studies, I focused mainly on aerodynamics and computational fluid dynamics, with particular attention to turbulence. In 2024 I moved to Stockholm to begin my doctoral studies at KTH within the Fluid and Surfaces group. In my PhD project, I am working with numerical simulations on the influence of Liquid-Infused Surfaces (LIS) in the control of transport properties.”

The PhD position below has been filled.

We have a PhD position open at FLOW KTH (potential postdoc candidates for the position can take contact me).

The position is funded by the ERC project LUBFLOW and will numerically investigate multiphase systems in shear flows.

The main purposes of this project are:

• Develop state-of-the-art efficient numerical solutions for interfacial turbulent flows
• Discover new physics and functions of liquid-infused surfaces in laminar and turbulent flows, including effects of surfactants, interfacial phenomena, particle dynamics, thermocapillary etc.
• Interact and contribute to the physical understanding of experimental observations related to other LUBFLOW projects.

This year’s research group day was about “science & cooking”, where we explored fluid mechanics in the kitchen, and of course cooked delicious food!

We are very happy to receive funding from European Research Council (ERC) Consolidator 2023 program. The project: LUBFLOW (Lubricant-infused surfaces in sUrfactant- and Bacteria-laden turbulent FLOWs) will establish the physics of liquid-infused surfaces in flow environments that contain turbulence, surfactants, and bacteria. The project builds upon the work carried out by past and current group members and collaborations with colleagues. In the coming months will announce a number of open positions!

We are happy to be on board WISE (Wallenberg Initiative Materials Science for Sustainability, wise-materials.org). WISE, funded by the Knut and Alice Wallenberg Foundation, is the largest-ever investment in materials science in Sweden and will encompass major efforts at Sweden’s foremost universities over the course of 10 years. The vision is a sustainable future through materials science.

We look forward to contributing to this vision!

In early 2023, we will recruit one postdoctoral student to work in mass transfer of liquid-infused material. Stay tuned!

This position has been filled!

We have an open postdoc position on investigating structured liquid-Infused Materials (LIMs) (Yasuga et al, Nature Phys, 17, 2021), which use a periodic solid scaffold to lock in liquid droplets.

The goal of this project is to evaluate the mass transfer capacity of LIMs. More information about the position and how to apply can be found here:
