Natural Draft Aeration of Stored Grain. Final Quarterly Progress Report, No. 4

摘要

It was discovered early in this work that wind induced flow would be of a much larger magnitude than natural draft induced air flow and has therefore been the subject of the rest of this effort. A computer program was written to approximate the amount of cooling done due to wind induced air flow through a grain bin filled with corn. The computer program has several features, the results of which are applicable to various bin diameter sizes. The computer program models the amount of air passing through a grain bin filled with corn. The greater the wind velocity, the greater the air flow through the bin. The program also models the size of an inlet duct to the bottom of the bin, as the larger the duct diameter the greater the air flowrate. Four quarterly progress reports are included.
