Solidity effects on the performance of vertical-axis wind turbines

open access: yesFlow, 2021
The variety of configurations for vertical-axis wind turbines (VAWTs) make the development of universal scaling relationships for even basic performance parameters difficult.

Flow forth

open access: yesFlow, 2021
The study of fluid flow has enabled milestones in technology and a deeper understanding of the natural world. Existing journals cover fundamental aspects of fluid mechanics very well and other journals target specific application fields.

Real-time flow measurement system: physics-informed reconstruction and sampling strategy

open access: yesFlow, 2023
In this work, we focus on a multi-hole pressure-probe-based flow measurement system for wind tunnel measurements that provides real-time feedback to a robot probe-manipulator, rendering the system autonomous. The system relies on a novel, computationally

Dynamics of cavity structures and wall-pressure fluctuations associated with shedding mechanism in unsteady sheet/cloud cavitating flows

open access: yesFlow, 2023
The physics and mechanism of sheet/cloud cavitation in a convergent–divergent channel are investigated using synchronized dynamic surface pressure measurement and high-speed imaging in a water tunnel to probe the cavity shedding mechanism.

Monitoring carbon dioxide to quantify the risk of indoor airborne transmission of COVID-19

open access: yesFlow, 2021
A new guideline for mitigating indoor airborne transmission of COVID-19 prescribes a limit on the time spent in a shared space with an infected individual (Bazant & Bush, Proceedings of the National Academy of Sciences of the United States of America ...

Theoretical modelling of the three-dimensional wake of vertical axis turbines

open access: yesFlow, 2021
Vertical axis turbine (VAT) arrays can achieve larger power generation per land area than their horizontal axis counterparts, due to the positive synergy from clustering VATs in close proximity.

Adaptive drag reduction of a sphere using smart morphable skin

open access: yesFlow
In this study, a novel smart surface-morphing technique is devised that dynamically optimises roughness parameter on a sphere with varying flow conditions to minimise drag. A comprehensive series of experiments are first performed to systematically study

Leveraging three-dimensionality for navigation in bluff-body wakes

open access: yesFlow
Biological flyers and swimmers navigate in unsteady wake flows using limited sensory abilities and actuation energies. Understanding how vortical structures can be leveraged for energy-efficient navigation in unsteady flows is beneficial in developing ...
