Abstract
The purpose of this study is to conduct an experimental investigation on granular fodder flow characteristics during discharge period in silos. The pressure on the silo wall and the mass flow rate of pellets feed stored in the silo for 1 hour were determined with the laboratory-scale steel and fiberglass silos. Additionally, the parametric study of four angles of a 55 mm diameter outlet conical hopper such as 10, 20, 30, and 45 degrees were done in this testing. From the results, the average wall pressure of the steel silo in the discharge period was more than that of the fiberglass silo. Both silos presented the minimum and maximum mass flow rate occurring on a hopper angle of 45 degrees and 10 degrees, respectively. When considering experimental results of the wall pressure and the average mass flow rate, it could be concluded that the flow patterns of granular fodder during discharge period in both steel and fiberglass silos were funnel flow patterns.
