Effect of Mistuning and Blade Passing Frequencies on a Turbine’s Integral Mode Blade Vibration Detection Using a Pulsation Probe

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2023
For engines operating using heavy fuel oil (HFO), the nozzle rings of turbocharger turbines are prone to severe degradation because of contamination with unburned fuel deposits. This contamination may lead to increased excitation of blade resonance.

Comparative Analysis of "Turbo", "Reduced-Turbo", "Flower" and "Semi-Turbo" Roundabout

open access: yesTehnicki vjesnik - Technical Gazette, 2020
A growing number of studies, presented in scientific and professional literature, point out a poor traffic safety characteristic of "standard" two-lane roundabouts, and lower capacity than expected. These problems are resolved in different ways in different countries; however, the most successful solution has proven to be reducing the number of ...

Current vehicle emission standards will not mitigate climate change or improve air quality

open access: yesScientific Reports, 2023
The vehicle emissions testing programme was conducted by the UK Department of Transport in 2016 in response to emissions tampering exposed in the Volkswagen (VW) emissions scandal. The programme identified large emissions discrepancies between real-world

Orbit Decomposition Method for Rotordynamic Coefficients Identification of Annular Seals

open access: yesApplied Sciences, 2021
The elliptical orbit whirl model is widely used to identify the frequency-dependent rotordynamic coefficients of annular seals. The existing solution technique of an elliptical orbit whirl model is the transient computational fluid dynamics (CFD) method.

THE ROAD SAFETY AT TURBO ROUNDABOUTS IN POLAND [PDF]

open access: yesArchives of Transport, 2015
There are to two groups of turbo roundabouts used currently in Poland. The first group is turbo roundabouts with geometry and traffic organization designed following the model of Dutch turbo roundabouts with raised lane dividers. The other group is turbo

Entanglement-assisted quantum turbo codes [PDF]

open access: yes, 2013
An unexpected breakdown in the existing theory of quantum serial turbo coding is that a quantum convolutional encoder cannot simultaneously be recursive and non-catastrophic.

Linear and nonlinear modeling of self-excited acoustic oscillations in a T-shaped thermoacoustic engine

open access: yesAIP Advances, 2021
Branch tubes are often used in thermoacoustic engines (TAEs) for acoustic power extraction or acoustic field adjustment. Their roles, although critical for the performance of the thermoacoustic system, are not fully understood yet. To address this issue,
