Comparison of the FFD simulation speeds on CPU and GPU

This investigation conducts simulations for airflow motion and airborne contaminant transportation in buildings on a Graphic Processing Unit (GPU). The GPU uses parallel programming structure that is very suitable for enhancing flow simulation speed. When the grid number is large, the Fast Fluid Dynamics (FFD) scheme on GPU can run around 30 times faster than it does on Central Processing Units (CPU). By using the FFD on the GPU, it is possible to simulate the airborne contaminant transport in large buildings at a speed faster-than-real-time.
