Abstract

Based on conventional design concept of the fan

the procedure of the parametric design and numerical simulation with application to the axial-flow fan is developed.The procedure and aerodynamic design process of the CPU fan are embodied into parametric design and numerical simulation software utilizing VB language as well as axial-flow fan aerodynamic design software

which can generate high quality HEXA mesh automatically.The numerical simulation can also be performed continuously by batch program and the results about performance curve of the fan can be characterized without resorting to anyone.At last geometry parametric investigations achieved quickly by the procedure are carried out to illustrate the effect of various design parameters on the performance of the fan by choosing one parameter at a time as the control variable

which can provide a more in depth understnding of the flow characteristic of the fan and deep understanding for the optimum of the fan.The procedure can be adopted widely to help engineers to improve work efficiency in practice.
