Directional and self-propelled flow in open channels has a variety of applications, including microfluidic and medical devices, industrial filtration processes, fog-harvesting, and condensing apparatuses. Here, we present versatile three-dimensional-...

Modeling the dynamics of partially wetting droplets on fibers (2022)
Journal Article
Christianto, R., Rahmawan, Y., Semprebon, C., & Kusumaatmaja, H. (2022). Modeling the dynamics of partially wetting droplets on fibers. Physical Review Fluids, 7(10), Article 103606. https://doi.org/10.1103/physrevfluids.7.103606

We simulate gravity-driven dynamics of partially wetting droplets moving along a fiber using the lattice Boltzmann method. For the so-called clamshell morphology, we find three possible dynamic regimes upon varying the droplet Bond number and the fib...

A robust and memory-efficient transition state search method for complex energy landscapes (2022)
Journal Article
Avis, S. J., Panter, J. R., & Kusumaatmaja, H. (2022). A robust and memory-efficient transition state search method for complex energy landscapes. The Journal of Chemical Physics, 157(12), Article 124107. https://doi.org/10.1063/5.0102145

Locating transition states is crucial for investigating transition mechanisms in wide-ranging phenomena, from atomistic to macroscale systems. Existing methods, however, can struggle in problems with a large number of degrees of freedom, on-the-fly a...

A minimal model of elastic instabilities in biological filament bundles (2022)
Journal Article
Panter, J., Kusumaatmaja, H., & Prior, C. (2022). A minimal model of elastic instabilities in biological filament bundles. Journal of the Royal Society. Interface, 19(194), Article 20220287. https://doi.org/10.1098/rsif.2022.0287

We present a model of a system of elastic fibres which exhibits complex, coupled, nonlinear deformations via a connecting elastic spring network. This model can capture physically observed deformations such as global buckling, pinching and internal c... Read More about A minimal model of elastic instabilities in biological filament bundles.

Spontaneous phase separation of ternary fluid mixtures (2022)
Journal Article
Shek, A. C., & Kusumaatmaja, H. (2022). Spontaneous phase separation of ternary fluid mixtures. Soft Matter, 18(31), 5807-5814. https://doi.org/10.1039/d2sm00413e

We computationally study the spontaneous phase separation of ternary fluid mixtures using the lattice Boltzmann method both when all the surface tensions are equal and when they have different values. To rationalise the phase diagram of possible phas... Read More about Spontaneous phase separation of ternary fluid mixtures.

Systematic characterization of effect of flow rates and buffer compositions on double emulsion droplet volumes and stability (2022)
Journal Article

Systematic characterization of effect of flow rates and buffer compositions on double emulsion droplet volumes and stability. Lab on a Chip, 22(12), https://doi.org/10.1039/d2lc00229a

Double emulsion droplets (DEs) are water/oil/water droplets that can be sorted via fluorescence-activated cell sorting (FACS), allowing for new opportunities in high-throughput cellular analysis, enzymatic screening, and synthetic biology. These appl... Read More about Systematic characterization of effect of flow rates and buffer compositions on double emulsion droplet volumes and stability.

Development of a setup to characterize capillary liquid bridges between liquid infused surfaces (2022)
Journal Article

Capillary liquid bridges are ubiquitous in nature and are present in many industrial processes. In order to model their behavior, it is essential to develop suitable experimental tools that are able to characterize the bridges’ geometry and the assoc...
