Term “Structured Convection” refers to natural convection driven by patterns of heating. This convection is different from the classical Rayleigh-Bénard convection as it occurs regardless of the heating intensity as well as regardless of the position of the heating sources. Fluid movement is driven by density gradients but prediction of the system response is complicated due to spatial parametric resonance effects. A review of the recent results will be presented, primarily from the point of view of drag reduction associated with such convection.
