Selection of the Electric Drive for the Wood Waste Compacting Unit

open access: yesEnergies, 2022
This work presents the study of the compaction and unloading process wood post-production waste, i.e., oak sawdust. The sawdust was compacted employing the forces F = 5000, 10,000, 20,000, 30,000, 40,000 and 50,000 N. Each compacted sample was compressed

Two-scale momentum theory for very large wind farms [PDF]

open access: yes, 2016
A new theoretical approach is proposed to predict a practical upper limit to the efficiency of a very large wind farm. The new theory suggests that the efficiency of ideal turbines in an ideal very large wind farm depends primarily on a non-dimensional ...
