AbstractThe transition process to turbulence is studied experimentally in thermocapillary convection of floating half zone. The onset of temperature oscillations in the liquid bridge of floating half zone and further transitions of the temporal convective behaviour are detected by temperature measurements in the liquid bridge. The fast Fourier transform (FFT) reveals the frequency and amplitude characteristics of the flow transition. The experimental results indicate the existence of a sequence of period-doubling bifurcations that culminates in turbulence. The measured Feigenbaum numbers are δ2 = 4.69 and δ4 = 4.6. Both results can be compared with the theoretical asymptotic value δ = 4.669.
