We present two dark energy (DE) models with an anisotropic fluid in Bianchi type-V I 0 space-time by considering time dependent deceleration parameter (DP). The equation of state (EoS) for dark energy ω is found to be time dependent and its existing range for derived models is in good agreement with the recent observations. Under the suitable condition, the anisotropic models approach to isotropic scenario. We also find that during the evolution of the universe, the EoS parameter for DE changes from ω > −1 to ω = −1 in first model whereas from ω > −1 to ω < −1 in second model which is consistent with recent observations. The cosmological constant is found to be a positive decreasing function of time and it approaches a small positive value at late time (i.e. the present epoch) which is corroborated by results from recent type Ia supernovae observations. The cosmic jerk parameter in our derived models is also found to be in good agreement with the recent data of astrophysical observations. The physical and geometric aspects of both the models are also discussed in detail.

The study of fluid flow problems through porous channel is very important in all the fields of engineering, astrophysics, bio-medicines, meteorology, oceanography and other related disciplines. When such flows occur in the presence of magnetic field, various parameters present in the motion become more effective and shows significant behavior in the velocity. In this paper an attempt has been made to find the effect of inclined magnetic field on the flow pattern of the fluid. After forming the governing differential equations, their solutions have been derived by assuming suitable boundary conditions, after this a graphical study has been done to examine the effects of various parameters. It has been found that the magnetic field is very effective in controlling the velocity in presence of other parameters and this can be utilized in industries.
