On similarity of pulsating regimes in Hele-Shaw cell
The results of direct numerical simulation of the convection in Hele - Shaw cell have been present­ed. The specific pulsating flows that originate in conditions of heating from below have been con­sidered theoretically by the method of finite difference. Amplitude-frequency characteristics are re­ceived for this self-oscillating flow. The spectrums similarity for pulsating regimes has been found in wide range of over-criticality values for the Hele - Shaw cell with different ratio of wide bounda­ries.
