In this project, steady air flow in a storage container room with two walls is investigated. Container rooms are often used for storage of industrial goods which are perishable and are required to be kept under influence of steady air flow for purpose of cooling and ventilation. In present work, steady air flow is simulated in a 0.5 * 0.5 * 1 room with to walls against air flow path which represent containing chamber. Air enters the domain with velocity equal to 5 m/s and reaches maximum velocity of approximately 20 m/s in the domain after flowing over the second wall. Structure of the walls generate a vortex between them which is shown in results.
Storage Container Room Geometry and mesh
Geometry of fluid domain is designed in Design Modeler and computational grid is generated using ANSYS Meshing. Mesh type is structured and element number is 115635.

Results and discussion
Air velocity at inlet is equal to 5 m/s which due to geometry specifications of the problem reach a maximum value of 20 m/s. Normal force exerted on the walls in the domain is equal to 15.8526 [N]. We can observe the extreme turbulence in space between two walls where turbulent kinetic energy reaches values up to 2 j/kg.
There is a mesh file in this product. By the way, the Training File presents how to solve the problem and extract all desired results.s
