Abstract: As sewer pipes age, groundwater and the surrounding soil can enter into the sewer system through various defects on the pipe wall. Groundwater infiltration and soil erosion through cracked sewer pipes can result in increased ...

Abstract: This paper presents the findings from an experimental investigation that was conducted to assess the shear behavior and the changes in the shear behavior and strength parameters for cemented paste backfill (CPB)–CPB interface ...

Abstract: This paper studies soil-erosion problem around cracked sewer pipes, which is usually associated with groundwater infiltration in sewer systems. Four factors (soil-particle size, defect size, water head, and soil height) ...

Abstract: Numerical investigations on the performance of the miniature centrifugal compressor in a SR-30 minijet engine are conducted in this study. A numerical framework is built on the basis of the grid independence and wall ...
