Liquid crystal displays have a myriad of applications, from simple thermometers to mobile phones, computer and TV screens. They have impacted our lives, invading our houses, transportation and workplaces. With the present online culture and increasing demands for energy efficiency has come the need for displays that can be read in all kinds of lighting conditions and limit the drain from the ba...

Quantum dot/liquid crystal nano-composites are promising new materials for a variety of applications in energy harvesting, displays and photonics including the liquid crystal laser. To realize many applications, however, we need to control and stabilize nano-particle dispersion in different liquid crystal host phases and understand how the particles behave in an anisotropic fluid. An ideal syst...

In this paper, we use Stokes, Brinkman and Darcy equations to approximate the porous continuum media of ligament tissues respectively, simulate the flow field with FLUENT software, and study the shear stress on the cell surface due to the interstitial fluid flow. Since the Brinkman equation approaches Stokes equation well in high hydraulic permeability (k p) condition (k p ≥1.0×10(-8) m(2) in o...

It has long been recognised that at elevated temperatures surface energy is the driving force for the distribution of melts and fluids among crystalline grains. While for ideal isotropic systems only two parameters, the dihedral angle (the ratio of grain boundary energy to solid-liquid surface energy) and the melt fraction are needed to completely constrain the melt distribution, anisotropic sy...

It is shown that unlike the perfect fluid case, anisotropic fluids (principal stresses unequal) may be geodesic, without this implying the vanishing of (spatial) pressure gradients. Then the condition of vanishing four acceleration is integrated in non-comoving coordinates. The resulting models are necessarily dynamic, and the mass function is expressed in terms of the fluid velocity as measure...

The possibility of strange stars mixed with dark energy to be one the candidates for is main issue present study. Our investigation shows that quark matter acts as after a certain yet unknown critical condition inside stars. proposed model reveals feature physically acceptable stable mimic characteristics plausible connections are shown through mass-radius relation well entropy and temperature....

An accurate description of the fluid flow and heat transfer within a Pressurized Water Reactor (PWR), for the safety analysis and reactor performance is always desirable. In this paper a mathematical model of the fundamental physical phenomena which are associated to a typical PWR is presented. The mathematical model governs the fluid dynamics in the reactor. Using commercial software CFX, a co...

The concept of complexity for dynamical spherically symmetric dissipative self-gravitating configuration (Herrera et al. Phys. Rev. D, 98, 104059 (2018). doi:10.1103/PhysRevD.98.104059) is generalized in the scenario modified Gauss–Bonnet gravity. For this purpose, a fluid with locally anisotropic, dissipative, and non-dissipative configurations considered. We choose same factor structure as we...

The propagation of a longitudinal wave in an anisotropic cylindrical bar immersed in water is considered. Energy is leaked into the surrounding fluid in the form of traveling waves, and this leakage determines the amplitude of the signal in the rod. This aspect is important in nondestructive evaluation of composite rods. The governing equation of the longitudinal waves traveling in the rod is o...

In the context of brane cosmology, a scenario where our universe is a 3 + 1dimensional surface (the “brane”) embedded in a five-dimensional spacetime (the “bulk”), we study geometries for which the brane is anisotropic — more specifically Bianchi I — though still homogeneous. We first obtain explicit vacuum bulk solutions with anisotropic three-dimensional spatial slices. The bulk is assumed to...
