Direct numerical simulation of 'short' laminar separation bubbles with turbulent reattachment [PDF]
, 2000 Direct numerical simulation of the incompressible Navier–Stokes equations is used to study flows where laminar boundary-layer separation is followed by turbulent reattachment forming a closed region known as a laminar separation bubble.

AN IMPROVED TURBULENCE MODEL FOR ROTATING SHEAR FLOWS
Proceeding of Second Symposium on Turbulence and Shear Flow Phenomena, 2001 In the present study, we construct a turbulence model based on a low-Reynolds-number non-linear k–ϵ model for turbulent flows in a rotating channel. Two-equation models, in particular the non-linear k–ϵ model, are very effective for solving various flow problems encountered in technological applications.

Direct numerical simulation of a decelerated wall-bounded turbulent shear flow [PDF]
, 2003 A fully developed turbulent channel flow is subjected to a mean strain that approximates that in a spatially developing adverse-pressure-gradient (APG) boundary layer. This is done by applying uniform irrotational temporal deformations to the flow domain

Advanced Materials Technologies, EarlyView.We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...

Nonlinear optimal perturbations in a Couette flow: bursting and transition [PDF]
, 2013 This paper provides the analysis of bursting and transition to turbulence in a Couette flow, based on the growth of nonlinear optimal disturbances. We use a global variational procedure to identify such optimal disturbances, defined as those initial ...

Optimization of Magnetic Milli‐Spinner for Robotic Endovascular Intervention
Advanced Robotics Research, EarlyView.This work presents the design optimization of a multifunctional magnetic milli‐spinner for high‐speed propulsion and efficient clot debulking. The optimized design achieves an ultrafast swimming velocity of 55 cm/s (≈175 body lengths/s) in saline water, enabling stable upstream swimming against strong physiological flows and establishing magnetic milli‐

Small-Scale Anisotropy in Stably Stratified Turbulence; Inferences Based on Katabatic Flows
Atmosphere, 2023 The focus of the current study is on the anisotropy of stably stratified turbulence that is not only limited to large scales and an inertial subrange but also penetrates to small-scale turbulence in the viscous/dissipation subrange on the order of the ...

Turbulent bubbly flow in pipe under gravity and microgravity conditions [PDF]
, 2012 Experiments on vertical turbulent flow with millimetric bubbles, under three gravity conditions, upward, downward and microgravity flows (1g, -1g and 0g), have been performed to understand the influence of gravity upon the flow structure and the phase ...
