A fully operational office space was created within the dimensions of a 20-foot ISO container. It was designed to be movable, when fitted on a conventional trailer. While the container would typically be sheltered from incoming wind by the towing vehicle, in the case of crosswind the danger of toppling increases significantly. In order to ensure its safe transportation, the performance of the container encountering crosswind when moving at high speed was investigated with the use of CFD. Fluid flow around blunt objects is well established as time-dependent problem, requiring many computational hours. Optiphore’s work focuses on:
- The construction of a computational mesh around the container office with Altair’s Hypermesh.
- The performance of CFD simulations of flow around the container geometry considering air speed and angle of attack as a result of the vehicle’s movement and the crosswind intensity. All simulations are performed with Altair’s Acusolve.
- Evaluation of the wind’s effective loading on the container outer wall to assess its stability.
- Visualization of the flow pattern with Altair’s AcuFieldView.
The problem of HVAC and thermal comfort inside the work environment was also tackled. Composite, “sandwich” walls where calculated to increase heat insulation, and a glass panel was added for lighting during the day. HVAC was designed so that heating and cooling would be made possible with the use of a ducted air conditioning unit. To assess the efficiency of the heating system, the locations of greater heat loss had to be pinpointed. For this task, CFD simulations of the air flow within the container coupled with heat transfer through the container walls were performed. Optiphore’s work focuses on:
- The construction of conforming computational mesh of the container’s walls and internal air volume with Altair’s Hypermesh.
- The performance of CFD simulations of the coupled problem of heat transfer due to conduction within the container walls, and convective heat transfer due to air movement at the container’s interior. All simulations are performed with Altair’s Acusolve.
- Assessment of heat loss due to different building materials used on the walls, floor, ceiling and the heating ducts.
- Visualization of the flow and heat pattern with Altair’s AcuFieldView.
