Experimental and Numerical Analysis of the Flow Inside a Configuration Including an Axial Pump and a Tubular Exchanger [PDF]

, 2010
In centrifugal and axial pumps, the flow is characterized by a turbulent and complex behavior and also by physical mechanisms such as cavitation and pressure fluctuations that are mainly due to the strong interactions between the fixed and mobile parts ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Hydrodynamic and Flow Field Characteristics of Water Jet Propulsion under Mooring Conditions

Journal of Marine Science and Engineering, 2022
The acceleration characteristics of a water jet-propelled ship during startup are related to its performance under mooring conditions. Water jet propulsion cavitation during startup increases the vibration and noise of the whole ship.

Study on the Water Jet Water Pump

Transactions of the Japan Society of Mechanical Engineers, 1954
The Author has determined the optimum dimensions of the jet pump by systematic experiments. (a) The length from the outlet of nozzle to the inlet of diffuser throat should be less than 1.5dt (dt=diameter of diffuser throat), and the length from the outlet of nozzle to the inlet of diffuser divergent part should be 5∼6dt.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

The importance of the knowledge of flow stream in water sump pump [PDF]

, 2013
Numerous different experimental and numerical methods have been developed and are already improved in order to get rather good flow descriptions inside pump components. These calculations are generally realized assuming uniform and steady flow conditions,

Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

Advanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.
