Abstract:The observation data of interfacial morphological evolution of the isolation layer were fitted by Origin software, and the parameters of Gauss model were analyzed theoretically and statistically, and the dynamic function expression of the whole interfacial profile of isolation layer was established. Then, actual measured curves of isolation layer and dynamic function expression were compared, and the function expression of bottom shape which is similarly a parabola was derived, and the function boundary point coordinates were solved on the basis of mechanical analysis. The mathematical model of interfacial morphology of whole isolation layer was constituted by these two function expressions. Research results could be regarded as a solid foundation for the construction of the loose medium flow field theoretical system with flexible isolation layer.
