ABSTRACT

In the world of industry and agriculture, efficient storage solutions are really important. Among these, storage silos stand out as significant symbols of effective storage management. They're essentially large cylinders built to store a variety of items, from grains to cement. They play a vital role in safeguarding materials and simplifying logistical tasks. Yet, they're more than just oversized containers. Silos also keep things in good condition by protecting them from things like moisture and pests. This study seeks to explore how external climatic conditions, as represented by the Biot number at the top of silo, affect the behavior of grains within. Two types of silos with different aspect ratios are analyzed to identify any noticeable trends or distinctions. The governing equations, along with their boundary conditions, are solved using the finite volume method. In results section, the thermal and dynamic performance of silo is discussed and documented.

Keywords: Darcy model; Granular silo; Heat transfer; Porous medium; Unventilated silo
