Abstract

An analysis of the results of numerical experiments in which the two-dimensional flow near a plate placed across an ascending fluid current was simulated is presented. The plate temperature was higher than that of the fluid. Fluid flows with a Prandtl number 0.25 ≤ Pr ≤ 7 were considered on the moderate Reynolds and Richardson number ranges 25 < Re ≤ 100 and 0 ≤ Ri < 20. Under these conditions, two flow patterns were observable, which differed from each other by the intensity of the transverse oscillations of a system consisting of attached twin vortices and the near wake. For different Prandtl numbers, in the (Re, Ri1/2) plane the pattern stability boundaries were established, together with the distinctive features of pattern-to-pattern transition. It was found that the vortex arrangement in the wake above the heated plate can differ from that in the von Kàrmàn street in the absence of buoyancy
