Aerodynamic drag reduction of heavy vehicles using append devices by cfd analysisMehrdad khosravi1, Farshid Mosaddeghi2, Majid Oveisi3, Ali khodayari-b4(1. Young Researches and Elite Club, Borujerd..., Iran;4. Department of Mechanical Engineering, Urmia University, Urmia, Iran)Abstract:Improving vehicle fuel consumption, performance and aerodynamic efficiency by drag reduction especially in heavy......
ferric-pseudobrookite phase was found at higher temperature. Direct reduction of oxidized sample-coke cylindrical briquettes was successfully achieved for phase transition from titaniferous magnetite... and air atmospheres. The oxidized pretreated ore is characterized by XRD and SEM. Finally, the direct reduction behaviour of the oxidized ore-coke briquettes is investigated and characterized. 2......
