The Two-Dimensional Liquid Crystal Droplet Problem with a Tangential Boundary Condition

نویسندگان

چکیده

This paper studies a shape optimization problem which reduces to nonlocal free boundary involving perimeter. It is motivated by study of liquid crystal droplets with tangential anchoring condition and volume constraint. We establish in 2D the existence an optimal that has two cusps on boundary. also prove droplet chord–arc curve its normal vector field VMO space, arc-length parameterization belongs Sobolev space $$H^{3/2}$$ . In fact, curves such closely resemble so-called Weil–Petersson class planar curves. addition, asymptotic behavior when becomes extremely large or small studied.

Dynamic and Deformation of a liquid Droplet in a Convective Two-Dimensional Laminar Flow

The objective of this research is to develop an accurate numerical method to be used in showing the deformation of a liquid fuel droplet in a convective field. To simultaneously solve the internal liquid droplet flow field as well as the external gas phase flow field, a nonstaggered rectangular grid system without any coordinate transformation is used. Transition from the gas field to the liqui...

Pergamon Asymptotic Behavior of Energy Solutions to a Two-dimensional Semilinear Problem with Mixed Boundary Condition

where: • f~ is a C °'1 and bounded domain in Rz; • 0f~ consists of two pieces F0 and F1, where the one-dimensional Hausdorff measure of F o is greater than 0; • F0 is smooth and F1 is piecewise smooth; • F0 and 1"1 are relatively closed in 0f~; • v is the unit outer normal of f~; • p is a large parameter. In this work, we shall only consider the least energy solutions, although the method can b...

Nvestigation of a Boundary Layer Problem for Perturbed Cauchy-Riemann Equation with Non-local Boundary Condition

Boundary layer problems (Singular perturbation problems) more have been applied for ordinary differential equations. While this theory for partial differential equations have many applications in several fields of physics and engineering. Because of complexity of limit and boundary behavior of the solutions of partial differential equations these problems considered less than ordinary case. In ...
