On the Stable-Oscillation Domain of a Simple Fluidic Oscillator

Journal of Fluid Science and Technology, 2009
A confined jet sometimes causes a self-exited oscillation due to the existence of a downstream target. In this work, the authors study this phenomenon.

Synthesis and Evaluation of Ceramic‐Anchored Cu‐Ce‐MnOx Catalyst for Low Temperature Reduction of Diesel Engine NOx Emissions Using Liquefied Petroleum Gas or Adblue as Reductants

Energy Science &Engineering, EarlyView.
LPG converting harmful NO represented by the dark smoke to harmless N2 and H2O shown by the white smoke over Cu‐Ce‐MnOx catalyst. ABSTRACT Manganese oxide‐based catalyst doped with copper and cerium was synthesized through microwave irradiation and successfully anchored on a ceramic support.

Experimental Investigation on Steam Generation Performance of a Solid Thermal Storage‐Based Steam Production System

Energy Science &Engineering, EarlyView.
1. Against the backdrop of the dual carbon goals and the transformation of the energy structure, traditional coal and natural gas boilers struggle to meet the demand for economical and stable steam supply in small and medium‐sized enterprises. In response, this study proposes a solid‐state thermal storage steam production system, aiming to provide a ...

Development of Hydrocarbon Flow Calibration Facility as a National Standard

Journal of Fluid Science and Technology, 2007
A new primary standard for hydrocarbon flow measurements has been constructed at National Metrology Institute of Japan (NMIJ). The facility was designed for the calibration of hydrocarbon flowmeters in the flow rate range between 3 and 300 m3/h.

CO2 capture by accelerated weathering of limestone using waste limestone at elevated CO2 concentrations

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Accelerated weathering of limestone (AWL) using waste limestone (WL) for industrially relevant CO2 capture remains underexplored. Previous studies on potable water‐operated AWL have mainly examined idealised conditions, such as the use of high‐purity limestone or relatively low CO2 concentrations, which may not reflect selected ...

Do the Manual or Computer-Controlled Flowmeters Generate Similar Isoflurane Concentrations in Tafonius?

Frontiers in Veterinary Science, 2019
Introduction: Tafonius is an anesthesia machine with computer-controlled monitor and ventilator. We compared the isoflurane fluctuations in the circuit with manual (MF) or computer-driven (CF) flowmeters, investigated the origin of the differences and ...

Determinants of Improved Dyspnea and Exercise Tolerance With Nasal High‐Flow O2 Therapy in Fibrotic Interstitial Lung Disease: A Pilot Physiological Study

Respirology, EarlyView.
We tested the respective effect of high‐flow and supplemental O2 from nasal high‐flow O2 therapy (NHFO2) on dyspnea and exercise tolerance in fibrotic interstitial lung disease. Supplemental O2 and NHFO2 (but not high‐flow) provided improvements in these outcomes at “iso‐O2 saturation” due to reduced ventilatory requirements.

Population Dynamics of Northern Pearl Dace Margariscus nachtriebi in Anthropogenically Altered Headwater Streams of the Nebraska Sandhills Ecoregion

River Research and Applications, EarlyView.
ABSTRACT Empirical evidence of population demographic responses to environmental perturbations is a major knowledge gap for aquatic vertebrate populations. Extensive habitat alteration including channelization of headwater streams influences the habitat template on which small‐bodied fish are dependent to carry out distinct life stages and maintain or ...
