Abstract: The efficiency of smoke extraction for longitudinal and transverse tunnel ventilation systems was studied in this paper by conducting numerical simulations using computational fluid dynamics (CFD). The smoke was assumed ...

Abstract: In this research, a vertical axis wind turbine (VAWT) with a Magnetic Levitation (Maglev) design was fabricated and tested. Numerical simulations were conducted to predict the magnetic flux distribution and generated voltage ...

Abstract: The effectiveness of the smoke control strategy plays an important role in increasing safety levels when fire accidents occur in road tunnels. This paper introduces clarifications about how the efficiency of smoke extraction ...

Abstract: Fire accidents in road tunnels can form a great danger in the life of people if the evacuation process does not happen effectively. This paper introduces a numerical investigation of fire and evacuation analysis in a road ...

Abstract: This study presents additional important findings to the results of the research paper; “Optimization of the efficiency of stall control using air injection for centrifugal compressors” published in the Journal of Engineering ...

Abstract: The casing treatment is an effective method for increasing the stall margin of compressors and enhancing the flow distribution at the blades tip. The present numerical study focuses on making an optimization of the casing ...

Abstract: Numerical investigation of the optimization of the stall control efficiency for a high speed centrifugal compressor using air injection is presented. External air was injected close to the diffuser entrance at the shroud ...
