Optical Micromanipulations based on Model Predictive Control of Thermoviscous Flows
Elena Erben, Ivan Saraev, Weida Liao +3
High-precision micromanipulation techniques, including optical tweezers and hydrodynamic trapping, have garnered wide-spread interest. Recent advances in optofluidic multiplexed as…
Modal analysis and optimization of swimming active filaments
John Severn, Eric Lauga
Active flexible filaments form the classical continuum framework for modelling the locomotion of spermatozoa and algae driven by the periodic oscillation of flagella. This framewor…
Axisymmetric thermoviscous and thermal expansion flows for microfluidics
Weida Liao, Eric Lauga
Recent microfluidic experiments have explored the precise positioning of micron-sized particles in liquid environments via laser-induced thermoviscous flow. From micro-robotics to…
Analytical methods for cytoplasmic streaming in elongated cells
Pyae Hein Htet, Eric Lauga
Cytoplasmic streaming, the coherent flow of cytoplasm, plays a critical role in transport and mixing over large scales in eukaryotic cells. In many large cells, this process is dri…
Rotational mobility in spherical membranes: The interplay between Saffman-Delbrück length and inclusion size
Marco Vona, Eric Lauga
The mobility of particles in fluid membranes is a fundamental aspect of many biological processes. In a 1975 paper [1], Saffman and Delbrück demonstrated how the presence of exter…
Effective extensional-torsional elasticity and dynamics of helical filaments under distributed loads
Michael Gomez, Eric Lauga
We study slender, helical elastic rods subject to distributed forces and moments. Focussing on the case when the helix axis remains straight, we employ the method of multiple scale…
