With the widely application of CFD in the field of HVAC (heating, ventilation and air conditioning), it is helpful to strengthen the competing capacities and improve the research capabilities of undergraduate students majored in building environment and facility engineering if they have some CFD knowledge. However, how to teach CFD to the undergraduate students is not very clear because of their limited knowledge. Based on our teaching practice, we discussed on the selection of CFD software for the teaching use, teaching contents and teaching methods, and assessment methods of CFD teaching.
