Electrochemical machining (ECM) is a non-traditional technology that widely used in the manufacturing of key components aviation industry. The current efficiency defined as ratio observed amount dissolved metal to theoretical predicted from Faraday’s law. In ECM, curve relates dissolution rate anode material and density. Accurate measurement basis for shape prediction cathode tool design. Howev...

To solve the housing damage problem of a fractured compressor blade (CB) caused by an impact on inner casing gas turbine in seventh stage (from 15 stages), modifications trailing edge (TE) CB have been proposed, namely 6.5 mm curved cutting and combination 4 straight with cutting. The simulation results both aerodynamics variables Cl Cd pressure ratio, including structural dynamics such as norm...

Casing deformation caused by fault and fracture sliding derived from fracturing has attracted growing attention. frequently occurs during the hydraulic process in Sichuan Basin. Although its mechanism been intensively studied, this issue is becoming increasingly severe demands immediate solutions, especially shale gas blocks of Changning-Weiyuan-Zhaotong. The present study summarizes analyzes r...

Extensive slug-test experiments have been performed at the Hydrogeological Experimental Site (HES) of Poitiers in France, made up of moderately fractured limestones. All data are publicly available through the "H+" database, developed within the scope of the ERO program (French Environmental Research Observatory, http://hplus.ore.fr). Slug-test responses with high-frequency (> 0.12 Hz) oscillat...
