CFD or Computational Fluid Dynamics is a branch of fluid dynamics, which solves fluid flow
governing equation using numerical methods(in the form of computer codes) to solve fluid flow problems.
In other words, CFD can simulate/predict fluid flow.
Since a CFD analysis can simulate a fluid flow scenario. We can use the CFD tool to predict the
flow profile of the area of interest and evaluate the effectiveness of the designed ventilation/AC system
during design stage. CFD gives the power of foresight by providing the HVAC engineer how his/her HVAC system
would perform. A CFD analysis can provide fluid velocity, temperature, RH & mass fraction of particles in the
area of interest.
