Flow pattern and stability of horizontal buoyant jets at low and moderate Re studied.
- class="label">•
Three flow patterns with unstable small-scale structures identified in the Re–Fr space.
- class="label">•
Substantive bifurcation previously reported not observed within the presumptive space.
- class="label">•
Concentration decay/spreading rates do not increase/decrease steadily in wider Re range.
- class="label">•
Our findings reconcile the contradictory Re-dependence in mixing previously reported.
