Time-dependent boundary conditions are ubiquitous in numerous natural and industrial flows. However, to date, the influence of such temporal modulations has been given minor attention. This research addresses ferrofluidic Couette flow between co-rotating cylinders a spatially homogeneous magnetic field subject time-periodic modulation. Using modified Niklas approximation, we study effect amplit...

We describe an adaptive particle-based technique for simulating incompressible fluid that uses an octree structure to compute inter-particle interactions and to compute the pressure field. Our method extends the hybrid Flip technique by supporting adaptive splitting and merging of fluid particles, and adaptive spatial sampling for the reconstruction of the velocity and pressure fields. Particle...

Tracking and observing multiple dynamic targets is an important task in mobile sensor networks. This paper presents a novel approach to the problem of sensor splitting/merging for mobile sensor networks to track and observe multiple targets in a dynamic fashion. In this approach, we propose a seed growing graph partition (SGGP) algorithm to solve the splitting/merging problem. Furthermore, duri...

Recent experiments have reported a novel transition to elasto-inertial turbulence in the Taylor–Couette flow of dilute polymer solution. Unlike previously transitions, this newly discovered scenario, dubbed vortex merging and splitting (VMS) transition, occurs centrifugally unstable regime mechanisms underlying it are two-dimensional: becomes chaotic due proliferation events where axisymmetric ...
