Pulsation Control in Pressure Metering Systems

Journal of Low Frequency Noise, Vibration and Active Control, 1994
Reliable pressure measurement in pulsating flow conditions is difficult. When an orifice meter is used, two significant errors can arise: the square root error, which is inherent to orifice plates, and the pressure distortion generated in the sensing lines and DP transmitter.

Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

Advanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

Radial stability analysis of the continuous pressure gravastar

, 2012
Radial stability of the continuous pressure gravastar is studied using the conventional Chandrasekhar method. The equation of state for the static gravastar solutions is derived and Einstein equations for small perturbations around the equilibrium are ...

Pentagonal 2D Altermagnets: Material Screening and Altermagnetic Tunneling Junction Device Application

Advanced Functional Materials, EarlyView.
From a database of 170 pentagonal 2D materials, 4 candidates exhibiting altermagnetic ordering are screened. Furthermore, the spin‐splitting and unconventional boundary states in the pentagonal 2D altermagnetic monolayer MnS2 are investigated. A MnS2‐based altermagnetic tunneling junction is designed and, through ab initio quantum transport simulations,

Simulation of Pressure Pulsations

, 2020
Utmattelsesbelastning er den primære årsaken til turbinskade i vannkraftverk. Syklisk belastning fra trykkpulsasjoner kan forårsake slik utmattelsesbelastning. Tilegning av informasjon om trykkpulsasjoner, og samspillet mellom turbin og vannvei, kan bidra til å unngå tidlig svikt i turbinene. Fenomenet kan studeres gjennom feltmålinger, men å utføre og
