Exact power series solutions of the structure equations of the general relativistic isotropic fluid stars with linear barotropic and polytropic equations of state.
At early times, the universe is predicted to have almost isotropic fluid that became anisotropic with the growth of cosmic time.
Let us start considering that the energy-momentum tensor for an isotropic fluid with a discoid shape and without heat flow can be written as
Through this technique optically isotropic fluid microstructure, dispersed with the dimension generally in the 1-150 nm range and formed spontaneous mixture from two immiscible liquids.
In this paper we have discussed the propagation of shear waves in a transversely isotropic fluid saturated porous layer resting on a homogeneous elastic half-space, lying under an elastic isotropic and homogeneous layer with rigid boundary with irregularity at the interface.
A transversely isotropic fluid saturated porous layer of thickness H2 resting on a homogeneous elastic half-space and lying under an elastic isotropic and homogeneous layer of thickness [H.sub.1] has been considered.
In order to investigate the effect of irregularity present in the transversely isotropic fluid saturated porous layer and to compare the results numerically between the phase velocity and the wave number, we will use the values of elastic constants given by Ding et al.
For x [member of] [-0.25,0.25] the medium is an isotropic fluid with speed 1, but outside of this region we have an anisotropic solid represented by the 2 x 2 matrix with 2 on the diagonal and 1 on the off-diagonal.
Therefore, a deep understanding of the interfacial dynamics is needed, not only in isotropic fluids with Newtonian flow properties, but also in anisotropic systems and in fluids that exhibit non-Newtonian behaviour.
Physically, this is a class of bar like elements such as isotropic fluids, animal blood, polymeric fluids and fluids with certain additives.
