Non-propagating magnetic hole solutions in anisotropic plasmas near the mirror instability threshold are investigated in numerical simulations of a fluid model that incorporates linear Landau damping and finite Larmor radius corrections calculated in the gyrokinetic approximation. This FLR-Landau fluid model reproduces the subcritical mirror bifurcation recently identified on the Vlasov-Maxwell...

We study charged fluid spheres under the 4-dimensional Einstein-Maxwell spacetime. The solutions thus obtained admitting conformal motion. We also investigate whether the solutions set provide electromagnetic mass models such that the physical parameters including the gravitational mass arise from the electromagnetic field alone. In this connection three cases are studied here in detail with th...

The mathematical model for the incompressible two-dimensional stagnation flow of a Maxwell fluid towards a shrinking sheet is proposed. The developed equations are used to discuss the problem of being two dimensional in the region of stagnation point over a shrinking sheet. The nonlinear partial differential equations are transformed to ordinary differential equations by firsttaking boundary-la...

Three-dimensional flow of non-Newtonian fluid induced by a stretching surface has been studied. The constitutive equations of Maxwell fluid are used. The surface possesses convective boundary conditions. Computations have been carried out for the non-linear problem. Convergence of the obtained solutions is discussed. Impact of the influential parameters involved in the heat transfer analysis is...

The aim of this paper is to study the influence vorticity on existence time in fluid systems for which global smoothness and decay are known case small irrotational data. We focus two examples: Euler–Korteweg system two-fluid Euler–Maxwell system. prove that lower bound lifespan these no less than inverse Hs (s>5∕2) norm rotational part initial velocity. Our approach based energy estimates fast...

One of the most important parameters in designing electrical motors is heat generation by the motor and the way it is dissipated. Temperature rising reduce efficiency and reliability of traction motors and leads to failure. In this paper, an urban train traction motor in a 3D computational fluid dynamics (CFD) simulation has been investigated. Maxwell software for electromagnetic simulation and...

The unsteady flows of an incompressible Oldroyd-B fluid between two infinite parallel plates are considered when the slippage between the plate and the fluid is valid. The relative velocity between the fluid and plate is assumed to be proportional to the shear rate at the plates. The flow is generated by moving one of the plates or application of the constant pressure gradient giving arise to t...

We consider multidimensional cosmologies in even-dimensional space-times (D = 2n) containg perfect fluid and a multidimensional generalization of the Maxwell field FA1···An preserving its conformal invariance. Among models with an isotropic physical 3-space some integrable cases are found: vacuum models (which are integrable in the general case) and some perfect fluid models with barotropic equ...

Ferrofluids are magnetic liquids comprised of magnetic nanoparticles coated with surfactants and suspended in a carrier fluid. With biomedical and pharmaceutical applications in mind, we study the motion and deformation of axisymmetric ferrofluid droplets in the presence of non-uniform magnetic fields. Here we carry out direct numerical simulations of interfacial dynamics of ferrofluid droplet ...
