sharp interfaceの例文

• The key is an atomically sharp interface between graphene and hyrogenated silicon.
• Unlike surface gravity waves, internal gravity waves do not require a sharp interface.
• The material featured ultra-thin and ultra-smooth layers with sharp interfaces.
• Most of these methods are either good in maintaining a sharp interface or at conserving mass.
• A phase field model can be constructed to purposely reproduce a given interfacial dynamics as represented by a sharp interface model.
• Within this medium, there is no sharp interface, but a continuous change of the refractive index that reduces Fresnel reflection.
• Alternatively, for sharp interfaces, the critical driving force will be very large, and most growth will occur by the lateral step mechanism.
• As phase field models became a useful tool in materials science, the need for even better convergence ( from the phase field to the sharp interface problems ) became apparent.
• 7 .  Phase field equations in the singular limit of sharp interface problems ( with X . Chen ) in IMA Volumes on Mathematics and its Applications 43, ( eds.
• In this case the only reference is the sharp interface model, in the sense that it should be recovered when performing the small interface width limit of the phase field model.
• To the south the forest meets the Bay of Bengal; to the east it is bordered by the Baleswar River and to the north there is a sharp interface with intensively cultivated land.
• In such a case the sharp interface limit ( i . e . the limit when the interface width goes to zero ) of the proposed set of phase field equations should be performed.
• A phase field model is usually constructed in such a way that in the limit of an infinitesimal interface width ( the so-called sharp interface limit ) the correct interfacial dynamics are recovered.
• Parameters of the model are then chosen by studying the limit of the model with this width going to zero, in such a way that one can identify this limit with the intended sharp interface model.
• The result gives a partial differential equation for the diffusive field and a series of boundary conditions at the interface, which should correspond to the sharp interface model and whose comparison with it provides the values of the parameters of the phase field model.
• A recent review of alternative energy density functions for interface tracking applications has proposed a modified form of the double-obstacle function which avoids the spontaneous drop shrinkage phenomena and limits on mobility, with comparative results provide for a number of benchmark simulations using the double-well function and the VOF sharp interface technique.
• This led to the development of phase field models of second order, meaning that as the interface thickness, \ varepsilon, becomes small, the difference in the interface of the phase field model and the interface of the related sharp interface model become second order in interface thickness, i . e ., \ varepsilon ^ 2.
• Other theoretical work contends that, " A sharp interface between quark matter and the vacuum would have very different properties from the surface of a neutron star "; and, addressing key parameters like surface tension and electrical forces that were neglected in the original study, the results show that as long as the surface tension is below a low critical value, the large strangelets are indeed unstable to fragmentation and strange stars naturally come with complex strangelet crusts, analogous to those of neutron stars.
