Research Interests

The research in the Cavitation and Interfaces Research Group is collaborative and interdisciplinary. My main research interests are within multiphase flow dynamics and particularly cavitation phenomenon. I have worked on cavitation from different point of views from diesel injection engines to biomedical engineering. Cavitation based on the applied perspective can be considered as an advantageous or disadvantageous mechanism. Besides, surface roughness modifications and liquid-solid interactions are among other research interests. In collaboration with Medical Engineering group at KTH, it is aimed to apply the extensive capability of the cavitation in new generation ultrasound contrast agents affected by acoustic droplet vaporization in medical application such as drug delivery and cell sorting.

Please contact Dr. Ghorbani and provide your resume for the possible openings on the research fields listed below.

Researches carried out in the Cavitation and Interfaces Research Group include, but are not limited to, the following:

1. Fabrication of novel micro/nanofluidic devices utilized in the characterization of the cavitating flow with different geometric and surface features 

This study is within the frame of TUBİTAK 3001 project led by Dr. Ghorbani. In particular, we fabricate the first generation of microfluidic devices capable of generating cavitating flow in turbulent flow conditions.

See some of the relevant publications:


2. Surface Roughness modification for intense cavitating flow generation in micro scale

In this study, we aim to enhance generation and intensification of cavitating flows inside microfluidic devices by developing artificial roughness elements and trapping hydrophobic fluorinated lubricants.


3. Utilization of perfluorodroplets and PVA microbubbles as different working fluids to study the physics of cavitation phenomenon

A part of this project is funded by KTH internal funding. Cavitation phenomenon is studied for different working fluids such as perfluoropentane droplets stabilized by cellulose nanofibers to achieve a flow map for the cavitating flow patterns in micro scale.

See some of the relevant publications:


4. Design, fabricate and develop biomedical device prototype based on small scale hydrodynamic cavitation

This study is funded in the frame of TUBİTAK 1003 scheme which is led by Prof. S. Ekici. Dr. Ghorbani is acting as a researcher in this project.


5. Engineering and Fabrication of Bubble / Gas Separation Filters Based on SLIPS Architecture

This study is a TUBİTAK 1001 project led by Dr. Ghorbani. The aim of this project is engineering electrospun mechanically durable copolymers containing charged units to absorb electrostatically charged polyelectrolytes and home-made silica nanoparticles in the range of 20nm to 100nm to create hydrophobic and hydrophilic fiber nets.


6. Acoustic droplet vaporization of novel perfluorodroplets stabilized by cellulose nanofibers (CNF).

This study is a collaborative work with Prof. Anna J. Svagan and Prof. Dmitry Grishenkov from KTH. It is shown that during the acoustic droplet vaporization (ADV) process, droplets are converted to gas-filled microbubbles, offering enhanced visualization by ultrasound. It is believed that the combined results make the CNF-stabilized droplets interesting in cell-droplet interaction experiments and ultrasound imaging.
