Machine learning acceleration of simulations of Stokesian suspensions (2019)
Journal Article
Kabacaoğlu, G., & Biros, G. (2019). Machine learning acceleration of simulations of Stokesian suspensions. Physical Review E, 99(6), Article 063313. https://doi.org/10.1103/physreve.99.063313

Particulate Stokesian flows describe the hydrodynamics of rigid or deformable particles in Stokes flows. Due to highly nonlinear fluid-structure interaction dynamics, moving interfaces, and multiple scales, numerical simulations of such flows are cha...

Mapping flagellated swimmers to surface-slip driven swimmers (2024)
Journal Article
Gidituri, H., Kabacaoğlu, G., Ellero, M., & Balboa Usabiaga, F. (2024). Mapping flagellated swimmers to surface-slip driven swimmers. Journal of Computational Physics, 510, Article 113081. https://doi.org/10.1016/j.jcp.2024.113081

Flagellated microswimmers are ubiquitous in natural habitats. Understanding the hydrodynamic behavior of these cells is of paramount interest, owing to their applications in bio-medical engineering and disease spreading. Since the last two decades, c...

Optimal design of deterministic lateral displacement device for viscosity-contrast-based cell sorting (2018)
Journal Article
Kabacaoğlu, G., & Biros, G. (2018). Optimal design of deterministic lateral displacement device for viscosity-contrast-based cell sorting. Physical Review Fluids, 3(12), https://doi.org/10.1103/physrevfluids.3.124201

We solve a design optimization problem for a deterministic lateral displacement (DLD) device to sort same-size biological cells by their deformability, in particular to sort red blood cells by their viscosity contrast between the fluid in the interio...

Cross-stream migration of a vesicle in vortical flows (2023)
Journal Article
Kabacaoğlu, G., & Lushi, E. (2023). Cross-stream migration of a vesicle in vortical flows. Physical Review E, 107(4), https://doi.org/10.1103/physreve.107.044608

We use numerical simulations to systematically investigate the vesicle dynamics in two-dimensional (2D) Taylor-Green vortex flow in the absence of inertial forces. Vesicles are highly deformable membranes encapsulating an incompressible fluid and the... Read More about Cross-stream migration of a vesicle in vortical flows.

Sorting same-size red blood cells in deep deterministic lateral displacement devices (2018)
Journal Article
Kabacaoğlu, G., & Biros, G. (2019). Sorting same-size red blood cells in deep deterministic lateral displacement devices. Journal of Fluid Mechanics, 859, 433-475. https://doi.org/10.1017/jfm.2018.829

Microfluidic sorting of deformable particles finds many applications, for example, medical devices for cells. Deterministic lateral displacement (DLD) is one of them. Particle sorting via DLD relies only on hydrodynamic forces. For rigid spherical pa... Read More about Sorting same-size red blood cells in deep deterministic lateral displacement devices.

Quantification of mixing in vesicle suspensions using numerical simulations in two dimensions (2017)
Journal Article
Kabacaoğlu, G., Quaife, B., & Biros, G. (2017). Quantification of mixing in vesicle suspensions using numerical simulations in two dimensions. Physics of Fluids, 29(2), https://doi.org/10.1063/1.4975154

We study mixing in Stokesian vesicle suspensions in two dimensions on a cylindrical Couette apparatus using numerical simulations. The vesicle flow simulation is done using a boundary integral method, and the advection-diffusion equation for the mixi...
