The cylinder flows structure is important part in the transverse-flow CO2 laser, which affects the
internal gas flow, and influences the flow kinetic energy loss. To study structural optimization to reduce the
flow kinetic energy loss is a key concern of designers. In this study, the dynamic mesh model is used to
simulate the rotation of cross-flow fan, the calculation process shows that it is easy to understand how to set
parameter and treat mesh. Through optimization analysis on six structure parameters of the cylinder flow, we
obtain the results that some of the parameters significantly influence the mixture gas velocity distribution in
the discharge domain, but some other parameters of the flow field less affected velocity distribution of the
discharge domain. The variation trends of the velocity distribution is also inconsistent which impacted by
variation of each parameter. Through comprehensive analysis, the results of the optimization are: α1 = 14; α2
= 67.9; α3 = 73.1; α4 = 9.5; α5 = 65.6; α6 = 41.7. By validation calculations for the optimized structure of
cylinder flow, we obtain the results that the flow state of discharge domain in the optimized structure is better
than that of the previous structure.
