摘要: Two parallel swirling/rotating jets with a distance between them are termed biswirling here, which have important and complicated vortex structures different from the single swirling jet due to negligible vortex-vortex interactions. The visualization of interaction is accomplished by using direct numerical simulation. evolution found rather complicated. turbulent kinetic energy turbulence dissipation in central convergence region augmented locally strongly. modulation jet-jet upon scales vortices dominated levels jets. intermediate small scale bijets not very high level at close smaller than that jets, whereas opposite true under far distance, so forth.
