风成沙纹的形成与沙的分选

Formation of aeolian ripples and sand sorting

Edgar Manukyan, Leonid Prigozhin

摘要:

我们提出了一个连续的模型,能够证明风成沙波纹的一些显着特点:现实的不对称的波纹形状,波纹增长的非线性阶段的波纹场的粗化,饱和度的波纹增长均匀的沙子,典型的粒度分离的沙子和粗颗粒的铠甲层的形成波纹波峰和迎风坡,如果沙子是不均匀的。

英文摘要:

We present a continuous model capable of demonstrating some salient features of aeolian sand ripples: the realistic asymmetric ripple shape, coarsening of ripple field at the nonlinear stage of ripple growth, saturation of ripple growth for homogeneous sand, typical size segregation of sand and formation of armoring layers of coarse particles on ripple crests and windward slopes if sand is inhomogeneous.
