Centrifugal Disc Spreading Quality as a Function of Feeding Position: Simulations and Experiments
Abstract
A combination of an improved analytical model for the description of particle motion on the spinning disc and hodographic ballistics in the air was described earlier. The unified model (Gindert-Kele, 2006) is considered nearly exact for single particles leaving a conical disc with pitched straight vanes. ”In-silico” spreading calculations with experimentally characterized particle clusters are sensitive to both spreader and fertilizer properties. However, parameters like loading area and air-drag coefficients may need empirical corrections. In this work experimental and simulated spreading patterns are compared demonstrating the importance of the angle selection for fertilizer feeding.Authors who publish with this journal agree to the following terms:
