Structure Design of Abrasive-Flat-Jet Nozzle for Cavity Completion of Horizontal Coalbed Methane Well

Shiyou jixie, 2021
The current hydraulic cave-making methods cannot determine the geometric size and shape of the caverns of vertical wells for coal-bed methane development, while the mechanical cavern-making method is prone to cutter bar deformation and tools falling into

Drag of a dispersion of nonhomogeneously structured flocs in a flow field [PDF]

Journal of Colloid and Interface Science, 2005
The influence of floc structure and floc concentration on the drag acting on a floc is investigated theoretically. A two-layer model is adopted to describe floc structure, and a cell model is used to simulate a floc dispersion. The influences of the key parameters of the problem under consideration, including floc concentration, Reynolds number, the ...
