概要
- 論文の詳細を見る
Marangoni instability is studied theoretically for a liquid layer with finite thickness, in which time-periodic heating (or cooling) at the bottom wall causes the surface tension gradient. In a static state of the layer, the heating gives a characteristic length which depends upon the time-period. Based upon this period, small disturbances are expressed by the Fourier series. It is shown that the critical Marangoni number and the corresponding wavenumber are given as functions of the Prandtl number, the coefficients of heat transfer, and the ratio of the characteristic length to the thickness of the layer. By truncating the coupling modes of disturbances at the lowest order, some typical results for the critical condition are discussed.
