Influence of bluff-body and swirl on mixing and intermittency of jets [PDF]

, 2010
In this paper we present the modelled results of turbulence, scalar mixing and intermittency for three different basic fluid dynamical problems using large eddy simulation (LES). The modelled problems are a turbulent round jet, a bluff body stabilised

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

Advanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

VELOCITY MEASUREMENTS IN CAVITATING FLOWS USING FAST X-RAY IMAGING [PDF]

, 2013
A promising method to measure velocity fields in complex two-phase flows such us cavitating flows is presented. Dynamics of the liquid phase and the bubbles are both investigated.

WALLDYN simulations of global impurity migration in JET and extrapolations to ITER [PDF]

, 2015
The migration of first wall material due to erosion, plasma transport and re-deposition is one of the key challenges in current and future fusion devices. To predict erosion/re-deposition patterns and to understand the underlying principal processes, the

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Cavitation Dynamics and Vorticity Analysis of a Clark-Y Hydrofoil and a Venturi Geometry Based on the DCM

International Journal of Rotating Machinery
Literature research has shown that the high turbulent viscosity of original Reynolds-averaged Navier–Stokes (RANS) models in the wake reduces the cavitation instability, resulting in an unreasonable performance prediction of the cavity generation ...

Re-Entrant Jet Modelling for Partially Cavitating Two-Dimensional Hydrofoils

, 2001
The computational analysis of partial sheet hydrofoil cavitation in two dimensions is performed. Particular attention is given to the method of simulating the flow at the end of the cavity.

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion

Advanced Robotics Research, EarlyView.
A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

Determination of Be sputtering yields from the spectroscopic observations at JET ILW based on 3D ERO modelling [PDF]

, 2013
Estimations of the ITER first wall (FW) lifetime, previously made using the three-dimensional Monte-Carlo ERO code (Borodin et al 2011 Phys. Scr. T145 014008), depend strongly on the assumptions of the physical sputtering yield for beryllium (Be).
