Davood Rahmatabadi Enayatolah Mohemi Hesam Moghadasi Moslem Tayebi Ramin Hashemi,

In this paper, the reasons of damage water pumps parts of the air compressor cooling system were studied. To reach this goal, the works like preparing metallographic samples, evaluation of structure, investigation of mechanical properties, the alloy parts detection and chemical analysis of deposit and corrosion products collected from the parts were performed. According to studies and results o...

Drilling boreholes is common practice in geotechnical and geoenvironmental investigations and in various other ex­ ploration, testing, and monitoring appli­ cations. When a casing is placed in a borehole an annular space is created be­ tween the casing and the surrounding soil. If not properly sealed, this annular space can be a potential path for trans­ port of contaminants in the subsurface e...

In the field of turbomachines, better engine performances are achieved by reducing possible parasitic leakage flows through the closure of the clearance distance between blade tips and surrounding casings. Together with new technologies involving higher casing conicity for improved compression rates, direct contact is now considered as part of aircraft engines normal life. In order to avoid pos...
