Indication of 310-Helix Structure in Gas-Phase Neutral Pentaalanine
We investigate the gas-phase structure of the neutral pentaalanine peptide. The IR spectrum in the 340-1820 cm-1 frequency range is obtained by employing supersonic jet cooling, infrared multiphoton dissociation, and vacuum-ultraviolet action spectroscopy. ...
AMER CHEMICAL SOC2023Cavitation bubble dynamics and microjet atomization near tissue-mimicking materials
Mohamed Farhat, Davide Bernardo Preso, Armand Baptiste Sieber
In recent years, considerable interest has been devoted to the interactions between cavitation bubbles and tissue-mimicking materials due to their promising applications in medicine and biomedical sciences. The strong fluid-structure interaction between a ...
AIP Publishing2023System and method for a microfluidic jet generation from a compact device
The invention discloses systems and methods for generation of microfluidic jets providing a tool for very precise and localized delivery of e.g., medicaments. The proposed solution overcomes shortcomings related to miniaturization of a jet injection techno ...
2021Plunging circular jets : Experimental characterization of dynamic pressures near the stagnation zone
Spillways are a requirement for dams' safety, mainly preventing dam over-topping in ood cases. A common spillway solution involves plunging jets which dissipate a considerable energy ow in the plunge pool. Dissipation has to occur in a controlled manner to ...
2021In-silico behavior of dissolved prolamins under electric field effect applied by electrospinning process using molecular dynamics simulation
This paper describes processing of alpha-zeins (Z19 and Z22) and alpha-gliadin (G) dissolved in aqueous ethanol under an electric field from a molecular viewpoint using molecular dynamics simulation. From the results, it was found that zeins dominated in h ...
ELSEVIER2021Application of particle-based numerical analysis to the practical design of Pelton turbine
François Avellan, Siamak Alimirzazadeh, Takashi Kumashiro
For the design optimization of the Pelton turbine, it is highly demanded to investigate the flow inside the turbine casing, which includes the water jet from the nozzles, the interaction between the jet and rotating runner, and the flow ejected from the bu ...
IOP PUBLISHING LTD2021Comparative study between Cubic and Ellipsoidal Fokker-Planck kinetic models
Motivated by improving the performance of particle-based Monte-Carlo simulations in the transitional regime, Fokker–Planck kinetic models have been devised and studied as approximations of the Boltzmann collision operator. By generalizing the linear drift ...
2019High-speed imaging of high pressures produced by cavitation bubbles
Mohamed Farhat, Danail Obreschkow, Outi Supponen
Cavitation bubbles, when correctly tuned, may provide interesting mechanical and chemical effects to their surroundings owing to their violent collapse. Such an event may produce high-speed liquid jetting, extreme heating, as well as pressures of thousands ...
SPIE-INT SOC OPTICAL ENGINEERING2019Duct modes damping through an adjustable electroacoustic liner under grazing incidence
Hervé Lissek, Romain Boulandet, Gaël Matten
This paper deals with active sound attenuation in lined ducts with flow and its application to duct modes damping in aircraft engine nacelles. It presents an active lining concept based on an arrangement of electroacoustic absorbers flush mounted in the du ...
2018The Role of Impeller Outflow Conditions on the Performance of Vaned Diffusers
Highly loaded impellers, typically used in turbocharger and gas turbine applications, exhaust an unsteady, transonic flow that is nonuniform across the span and pitch and swirling at angles approaching tangential. With the exception of the flow angle, conf ...
