Pseudospectrum in Rectangular Mini/Micro Channel Fluidics Linear Transition to Turbulence

IEEE Access
Recent years have seen a significant increase in interest in rectangular mini/micro channels, such as those found in high-power research reactors with plate-type fuels, high-performance microelectronic cooling systems, photovoltaic panel cooling systems,

Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

The Anatomical Record, EarlyView.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

Transition to turbulence in pulsating pipe flow

, 2017
Fluid flows in nature and applications are frequently subject to periodic velocity modulations. Surprisingly, even for the generic case of flow through a straight pipe, there is little consensus regarding the influence of pulsation on the transition ...

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

The Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

Physical modelling of colloidal slurry flows [PDF]

, 2008
The study looks at the rheology and pipeline flow properties of colloidal suspensions dispersed in electrolytes of different concentration and type. Fuso silica spheres (0.8pm) form the dispersed phase of the suspension, and KN03, KCI electrolytes the ...

Effect of Prandtl's ration on balance in geophysical turbulence

, 2015
Support for this research has come from the UK Engineering and Physical Sciences Research Council (grant no. EP/H001794/1).The fluid dynamics of the atmosphere and oceans are to a large extent controlled by the slow evolution of a scalar field called ...

Local correlation-based transition model for aerodynamic flows in wide speed range

Engineering Applications of Computational Fluid Mechanics
A local correlation-based transition model is developed for aerodynamic flows in a wide speed range. New localized methods for the momentum-thickness Reynolds number are introduced for constructing local transition indicators. New transition correlations

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

The Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

Effects of turbulence modelling on the analysis and optimisation of high-lift configurations [PDF]

, 2011
Due to the significant effects on the performance and competitiveness of aircraft, high lift devices are of extreme importance in aircraft design. The flow physics of high lift devices is so complex, that traditional one pass and multi-pass design ...
