Dusty fluids are utilized to minimize heat in systems like gas-freezing and nuclear-powered reactors, among other places. The present study aims investigate the effect of Newtonian heating on dusty fluid flow. Between two parallel plates, two-phase MHD fluctuating flow is considered. dust particles inside thought be spherical uniformly distributed. generation absorption were also taken into con...

In this paper we explore how far the post-Newtonian theory, [9] goes in overcoming the difficulties associated with anisotropic homogeneous cosmologies in the Newtonian approximation. It will be shown that, unlike in the Newtonian case, the cosmological equations of the post-Newtonian approximation are much more in the spirit of general relativity with regard to the nine Bianchi types and issue...

An exact solution of the unsteady free convection boundary-layer flow of an incompressible fluid past an inclined oscillating plate with the flow generated by Newtonian heating in the presence of radiation is presented here. The resulting coupled linear partial differential equations for the velocity, the temperature and the concentration are non-dimensionalized and their solutions have been ob...

although there are many excellent ways presenting the principle of the classical calculus, the novel presentations probably leads most naturally to the development of the non-newtonian calculus. the important point to note is that the non-newtonian calculus is a self-contained system independent of any other system of calculus. since this self-contained work is intended for a wide audience, inc...

In this paper, we have investigated the combined effects of Newtonian heating and internal heat generation/absorption in the two-dimensional flow of Eyring-Powell fluid over a stretching surface. The governing non-linear analysis of partial differential equations is reduced into the ordinary differential equations using similarity transformations. The resulting problems are computed for both se...

Abstract An exact analysis of heat transfer accompanied by mass transfer flow of a Casson fluid past an exponentially accelerated infinite vertical plate with Newtonian heating in the presence of radiation is presented here. The governing coupled linear partial differential equations are transformed into linear ordinary differential equations by using non-dimensional variables. The resulting eq...

In an irrotational dust universe, the locally free gravitational field is covariantly described by the gravito-electric and gravito-magnetic tensors Eab and Hab. In Newtonian theory, Hab = 0 and Eab is the tidal tensor. Newtonian-like dust universes in general relativity (i.e. with Hab = 0, often called ‘silent’) have been shown to be inconsistent in general and unlikely to extend beyond the kn...

We analyze three-dimensional magnetohydrodynamic (MHD) simulations of a nonradiative accretion flow around a black hole using a pseudo-Newtonian potential. The flow originates from a torus initially centered at 100 gravitational (Schwarzschild) radii. Accretion is driven by turbulent stresses generated selfconsistently by the magnetorotational instability. The resulting flow has three well-defi...

We carried out three-dimensional global resistive magnetohydrodynamic (MHD) simulations of the cooling instability in optically thin hot black hole accretion flows by assuming bremsstrahlung cooling. General relativistic effects are simulated by using the pseudo-Newtonian potential. Cooling instability grows when the density of the accretion disk becomes sufficiently large. We found that as the...

When a self-gravitating body (e.g., a neutron star or black hole) interacts with an external tidal field (e.g., that of a binary companion), the interaction can do work on the body, changing its massenergy. The details of this “tidal heating” are analyzed using the Landau-Lifshitz pseudotensor and the local asymptotic rest frame of the body. It is shown that the work done on the body is gaugein...
