COMPUTATIONAL FLUID DYNAMICS ANALYSIS (CFD)

GENERAL DESCRIPTION:

Computational fluid dynamics involves the discretization of the solution domain into finite volumes (control volumes) and the subsequent solving of the Navier-Stokes (conservation of momentum), conservation of mass, and conservation of energy equations. In addition, in this case, the buoyancy forces are also being considered.



IMPORTANT NOTE:

CFD analysis takes the complexity out of flow analysis and can be a regular part of your design process, reducing the need for costly prototypes, eliminating rework and delays, and saving time and development costs.




DESIGNED FOR

* Evaluate the performance of the natural ventilation system for summer and       winter conditions.

 

* Determine the air temperature and contaminant concentration distribution     throughout the entire potroom based on specified pot heat release and     emission rates.

 

* Confirm the sizing of the floor grating open area around the pot cells and near     the potroom walls, and confirm the sizing of the proposed roof ventilator.

 

* Establish damper settings in the roof ventilator for summer and winter     conditions.

 

* Evaluate the effects of wind on the performance of the natural ventilation     system.

 

METHODOLOGY

Computational fluid dynamics involves the discretization of the solution domain into finite volumes (control volumes) and the subsequent solving of the Navier-Stokes (conservation of momentum), conservation of mass, and conservation of energy equations. In addition, in this case, the buoyancy forces are also being considered.

 

 

OBJECTIVES

The ventilators keep rain and snow from entering the facility while allowing hot air to exit from the top of the roof structure. The objective of the analysis is to determine buoyant air flow characteristics of the ventilator and establish whether the ventilator meets the design requirements (building temperature rise).
