Experimental Study of Abrasive Waterjet Cutting for Managing Residues in No-Tillage Techniques

A laboratory investigation of abrasive waterjet cutting wheat straws was conducted. The work aimed at a systematic characterization the capability straws, as potential alternative to discs currently adopted in no-till drills and planters for crop residue management. two level 2IV7?3 fractional factorial design applied investigate influence process parameters on efficiency straws. Straw coverage thickness, water pressure, orifice diameter were found be most significant ones. Experimental results suggest that straw mechanism is mostly related hydraulic power jet. multiple logistic regression performed model relationship between jet power. then estimate average consumption during no-tillage seeding operation. An 6400 W would sufficiently high guarantee 90% presence heavy distribution. experimental study shows small quantity powder (50 g·min?1) allows one increase reduce required maximum power, compared pure cutting. Results show are potentially relevant field validation agriculture based no-tillage.
