수직평판 사이를 흐르는 두 점성 유체의 밀도차에 의한 새로운 계면의 불안정성 연구(II) -수치적 비선형 연구- 이철우; 주상우; 이상천;
A nonlinear evolution of the interface is observed when two vertical fluid layers of different densities flow between two parallel vertical plates. The existence of Rayleigh-Taylor instability, the effects of the density ratio and total flow rate in the vertical stratified flow are studied. An exact location of the interface is described by Spectral method and Fourier coefficients are recorded to check the evolution of the interface.
