A Review of Silo Temperature Field Studies

Abstract

Silo is a large thin-walled structure, due to the operation period will be affected by different temperatures, such as sunshine temperature difference, seasonal temperature difference and the temperature difference between inside and outside the silo wall, of which the most influential is the sunshine temperature difference, silo due to the unevenness of the temperature distribution is prone to stress concentration and more likely to occur damage. This paper briefly introduces the three-dimensional heat transfer theory and ASHRAE solar radiation model, and discusses in detail the research progress of different experts and scholars at China and abroad on the temperature effect of silos. Finally, it is concluded that there are fewer temperature regulations in China codes, and there is a need to develop a perfect temperature theory to prevent silos from damage caused by temperature inhomogeneity.
