With "rear-upward" moisture-removal grooves being provided on the middle-rear portion of stationary-blade cascade-pressure surfaces in the last stage of a steam turbine and through a full three-dimensional numerical simulation of two-phase flows,explored and investigated was the moisture-removal mechanism of the grooves in question.

Study on Pad Groove Design in Chemical Mechanical Polishing;

Analysis of tube burst resulted from the cavitation grooves on waterwall at the furnace arch of boiler;

In the paper, the vacuum infusion molding process based on grooves was investigated by experiments, and the parameters of width, d e pth and spacing for flow grooves and spacing for supply grooves were optimized a ccording on the molding experiments and various factors that had influence on th e mold filling process were discussed.

However, the rigid road surface poses strict requirements on proper roadbeds, whereas roads in town have many examining wells for underground pipes and grooves, which is potential threat to road surface and ~ cause its forepart breakage.
