Description of the project

The thermal comfort of industrial operators subjected to high temperatures is very important. Workers must be comfortable to work safely and effectively. There are several ways to improve thermal comfort in these environments.

Glass bottles are usually formed using a technique called blowing. In this process, a ball of molten glass is blown into a bottle-shaped mold. The edges of the ball are then stretched and rolled to form the bottle. Once the process is complete, the bottle is cooled and polished. Once the process is complete, the bottle is ready to be packed and shipped.

Creation of a digital study model

The creation of the model of the plant was carried out by taking into account the topology of the site with a great precision in order to be able to capture at most the evolution of the air flows. This digital twin takes up precisely the different sets of beams, the air volumes as well as the surrounding buildings.

This very marked precision for the realization of the numerical twin is translated into a flagrant gain on the veracity and the relevance of the results obtained during the CFD simulation.

Study of natural ventilation

The natural ventilation of a glass factory is a ventilation system that uses outside air to evacuate hot or stale air from inside the workshop. The system uses static aerators that are strategically placed to take advantage of outside air currents and the upward force of warm air to create an aeration air stream. Outside air is drawn in through openings located near the ground and warm air is expelled through openings located near the roof. Windows and doors are also used to help create air movement. If mastered, these systems can be very effective in providing sufficient ventilation for the operators.

Natural ventilation in industry is a system that works by using the force of the wind to create an air flow inside the buildings. The system is based on the principle of thermal convection, which is a natural process of heat transfer based on the temperature difference between the air inside and the air outside.

Optimization of air quality and thermal comfort

CFD (Computational Fluid Dynamics) simulation has helped optimize natural ventilation in industry by providing accurate and up-to-date information on the efficiency of ventilation systems.
