Pierce. The theory is applied to systems, such as binary fluid convection, that are described by coupled complex Ginzburg-Landau equations. As a result the TW and MW are tentatively identified with the confined travelling wave states and the blinking states, respectively, observed both experimentally and numerically in systems with sufficiently large Cited by: 4.

The researches on nonlinear science currently cause extensive concern all over the world. The natural phenomena which we usually see, such as the convection in atmosphere, the reservoir, the ocean and so on, are all in nonequilibrium open system away from heat equilibrium.

The deep research for these phenomena is indispensable both in harmonious coexistence between Author: Ning LiZhong, Wang YongQi, Yuan Zhe, LI KaiJi, HU Biao.

Table illustrates the thresholds of stationary convection for different modes. The critical Rayleigh number is given by R sup TC = R sup /(1 − Le), where R sup = ± for a T = a S = 0, and R sup = ± for a T = a S = 1 This expression is in perfect agreement with the results predicted by Charrier-Mojtabi et al.

and Mamou et al., b, Mamou et al., by: Abstract. Various papers on low-gravity fluid dynamics and transport phenomena are presented. Individual topics addressed include: fluid management in low gravity, nucleate pool boiling in variable gravity, application of energy-stability theory to problems in crystal growth, thermosolutal convection in liquid HgCdTe near the liquidus temperature, capillary surfaces in microgravity.

The stability of the parallel flow solution is studied and the threshold for Hopf bifurcation is determined. For a relatively large aspect ratio enclosure, the numerical solution indicates horizontally travelling waves developing near the threshold of the oscillatory convection.

Multiple confined steady and unsteady states are found to coexist. Combined natural convection and non-gray radiation heat transfer in a horizontal annulus.
