Abstract: Abstract： Flow bifurcations play a crucial role in elucidating the physical characteristics of flow fields, offering significant guidance for the flow problems encountered in engineering practice. For internal cavity flow fields, the geometric characteristics of the cavity significantly influence the types and critical values of flow bifurcations, while the impact patterns of certain geometric configurations on flow bifurcations remain unclear. In this paper, we employed numerical simulations and analyzed flow phenomena using the lattice Boltzmann method (LBM) based on a cartesian grid and stability analysis theory, focusing on quasi-honeycomb cavity configurations. It revealed the influence mechanisms of quasi-honeycomb geometries on flow bifurcations within internal flow fields. In comparison with previous research, we emphatically discussed the influence of quasi-honeycomb configurations on Hopf, Neimark-Sacker, and Turbulence-triggering flow bifurcations. The results indicate that although quasi-honeycomb configurations do not affect the type of flow bifurcations or the evolution patterns of flow field, they significantly impact the critical values of flow bifurcations. This effect effectively delays the onset of flow instability and turbulence, greatly enhancing the stability of internal flow fields.
