Hedge Lucerne Desmanthus virgatus Cutting Interval Cutting Height Yield Chemical Composition
2016/4/20
The experiment was conducted to determine the effects of cutting interval and cutting height on the yield and nutrient composition of hedge lucerne (Desmanthus virgatus) when grown on a sandy soil in ...
Hydrodynamic Model for the Plasma-Gas Flow in a Cutting Torch Nozzle
Hydrodynamic Model the Plasma-Gas Flow a Cutting Torch Nozzle
2010/10/26
We present a simple hydrodynamic model to obtain the profiles of the relevant physical quantities along a nozzle of arbitrary cross-section in a cutting torch. The model uses a two-zone approximation ...
Experimental Characterization of a Low-Current Cutting Torch
Experimental Characterization a Low-Current Cutting Torch
2010/10/26
An experimental characterization of a low-current (30-40 A) cutting torch is presented. To avoid contamination of the plasma arc by removed anode material, a rotating steel cylinder was used as the an...
