Effect of flow rate ratio and positioning on a lighthouse tip ECMO return cannula.

Published in Biomechanics and modeling in mechanobiology

Extracorporeal membrane oxygenation is a life-saving support therapy in the case of cardiopulmonary refractory failure. Its use is associated to complications due to the presence of artificial surfaces and supraphysiological stress conditions. Thus, knowledge of the fluid structures associated to each component can give insight into sources of bloo...

Machine-learning based optimization of a biomimiced herringbone microstructure for superior aerodynamic performance

Published in Engineering Research Express

Biomimicry involves drawing inspiration from nature’s designs to create efficient systems. For instance, the unique herringbone riblet pattern found in bird feathers has proven effective in minimizing drag. While attempts have been made to replicate this pattern on structures like plates and aerofoils, there has been a lack of comprehensive optimiz...

Effect of laryngeal jet on dry powder inhaler aerosol deposition: a numerical simulation

Although pulmonary drug delivery has been deeply investigated, the effect of the laryngeal jet on particle deposition during drug delivery with dry powder inhalers (DPI) has not been evaluated profoundly. In this study, the flow structure and particle deposition pattern of a DPI in two airway models, one with mouth-throat region including the laryn...

Investigation of viscous supersonic laminar flows around F-16 airfoil: experimental, numerical, and analytical approache...

Published in Physica Scripta

This research paper primarily focuses on the behavior of viscous supersonic laminar flows around the F-16’s NACA 64A-204 airfoil, while also extending its scope to Shock-Wave/Boundary-Layer Interactions. The aim is to evaluate and compare methodologies for accurately characterizing these crucial aerodynamic phenomena. A unique experimental setup wa...

Numerical Analysis of Tonal Noise Emissions from Open and Shrouded Contra-Rotating Propellers

As market growth projections for Urban Air Mobility vehicles (UAMs) skyrocket, their presence in urban environments is likely to become increasingly prevalent, as will their noise. This creates a disturbance to both humans and wildlife, previously unaffected by aircraft noise. Further reinforcing the concern is the new multi-rotor designs, which in...

Building Simulation Software for Indoor Air Quality Research: A Review

Published in IOP Conference Series: Earth and Environmental Science

In this digital era, information technology really helps the process of designing and designing a more efficient, durable, high-performance building. After the pandemic, indoor air quality (IAQ) becomes an important issue since human spend most of the time indoor, which can impact their well-being in the long term. Ventilation is considered as one ...

Physical and CFD model used in the analysis of particles dispersion.

Published in Heliyon

Air pollution, representing one of the major environmental crises affecting us all, is responsible for half a million deaths each year in Europe. This research shows a numerical model based on Computational Fluid Dynamics (CFD) and a methodology for its validation allowing to know the evolution of particles in open urban environments. In this case,...

Preliminary assessment of the NACA0021 trailing edge wedge for wind turbine application.

Published in Heliyon

The airfoil blade is the primary component of a wind turbine, and its aerodynamic properties play a crucial role in determining the energy conversion efficiency of these blades. Many researchers have proposed different airfoil modifications intending to enhance the aerodynamic characteristics and limit the unsteady interaction with the atmospheric ...
