The discourse on the application of green technology in maritime sector is an interesting agenda to implement. development world shipping transportation which continues experience increase numbers and services creates new problems terms fuel supply resulting emissions. So that innovation for ship machinery should be directly related fossil substitution technology, operational efficiency improvi...

In the present study, a computational fluid dynamics (CFD) method have been utilized to investigate the effects of exhaust gas recirculation (EGR) and initial charge pressure by means of using a supercharger on the emissions and performance of a SI engine. This engine is fueled separately by gasoline and two potential alternative fuels, hydrogen and ethanol. The results of simulation are compar...

This paper reports the improved model design of an auger thermo-radiation dryer for drying plant-derived pomace under a low-temperature mode (35...80 °C) to resulting moisture content at level 8...13 % solids. The has adjustable speed rotation (3...4 min–1), airflow (0.05...0.09 m/s), and is characterized by uniform distribution heat flux. It equipped with energy-saving two-circuit complex that...

The main focus of this study is to apply a computational tool for the flow analysis of the turbine engine that has been tested with ice crystal ingestion in the Propulsion Systems Laboratory (PSL) at NASA Glenn Research Center. The PSL has been used to test a highly instrumented Honeywell ALF502R-5A (LF11) turbofan engine at simulated altitude operating conditions. Test data analysis with an en...

The transition toward electrified mobility is rapidly accelerating, but sustainability challenges associated with batteries, including costs, raw materials, and manufacturing-related emissions, pose barriers. Here, we discuss the role of extreme fast charging in breaking down these barriers offering a pathway more sustainable battery-powered electric-vehicle market. transport sector accounts fo...
