Complex Flow Generation and Development in a Full-Scale Turbofan Inlet

Noise-Source Separation Using Internal and Far-Field Sensors for a Full-Scale Turbofan Engine

Performance evaluation of a full-scale ABS resin manufacturing wastewater treatment plant: a case study in Tabriz Petrochemical Complex

 Background: The measurement data regarding the influent and effluent of wastewater treatment plant (WWTP) provides a general overview, demonstrating an overall performance of WWTP. Nevertheless, these data do not provide the suitable operational information for the optimization of individual units involved in a WWTP. A full-scale evolution of WWTP was carried out in this study via a r...

Full-Scale Turbofan Engine Noise-Source Separation Using a Four-Signal Method

Contributions from the combustor to the overall propulsion noise of civilian transport aircraft are starting to become important due to turbofan design trends and expected advances in mitigation of other noise sources. During on-ground, static-engine acoustic tests, combustor noise is generally sub-dominant to other engine noise sources because of the absence of in-flight effects. Consequently,...

Fan Flow Deflection in Simulated Turbofan Exhaust

Fan flow deflection for jet noise reduction was applied to subscale nozzles simulating the geometry and exhaust conditions of separate-flow turbofan engines. Two types of deflectors were tested, one comprising two pairs of vanes internal to the fan duct and the other consisting of a wedge positioned outside the fan duct. The noise reduction achieved by the vanes was strong in the downward direc...

Development and validation of a tolerance scale in spouses’ relations

Abstract: Tolerance has an influential role in peace making and adjustment in marital life and helps couples to have a stable marital life. According to the Islamic teachings, tolerance is the best way of dealing with couples’ differences in their relationships. The current research aims to develop and validate a scale to measure tolerance in spouses’ relations based on the Islamic approach. Th...
