By using similarity analysis the governing differential equations are transformed into a set of non-linear coupled ordinary differential equations which are solved numerically. Numerical results were presented for velocity and temperature profiles for different par

The problem of heat and mass transfer of Sisko nanofluid flowing through a nonlinear stretching sheet under the influence of chemical reaction, heat source, magnetohydrodynamics, and thermal radiation is examined in this study. The controlling model equations are rendered dimensionless, and the resulting set of nonlinear ordinary differential equations are solved utilizing the shooting technique for the nondimensional velocity, temperature, and concentration profiles, along with Runge-Kutta-Fehlberg's method of fourth order.

Abstract:

An analysis is performed to study the effects of thermal radiation on unsteady free convective flow over a moving vertical plate with mass transfer in the presence of magnetic field. The fluid considered here is a gray, absorbing-emitting radiation but a non- scattering medium. The plate temperature is raised to T 0 and the concentration level near the plate is also raised linearly with time. The dimensionless governing equations are solved using the Laplace transform technique. The velocity, temperature and concentration are studied for different parameters like the magnetic field parameter,

Abstract:

Any FIELD, by definition, is Force, which is a continuous parameter of space. For the Magnetic Field, this parameter is the Ampere Force, but it was actually neglected. Without fully understanding the ELEMENTARY Lorentz Force, the mystical “Theory” of Magnetism was built - the theory of interaction of Descartes’ “gimlets”, which was used by Maxwell to build General Electrodynamics. This, strictly speaking, led to the uncertainty of the very concept of the Magnetic Field. So in practice, when designing magnets, the “Theory” of Magnetism actually did not work and was used by Kirchhoff’s rules ba

Abstract:

The effect of an applied magnetic field H0 on the low-temperature properties of highly anisotropic magnetic systems, in which superconductivity can coexist with spin density waves, is studied. A system of equations is obtained for two order parameters—the superconducting order parameter Δ and the magnetic order parameter M; the difference of the free energies of the superconducting and normal magnetic phases for the system in parallel (H0‖M) and perpendicular (H0⊥M) magnetic fields is determined. Numerical calculations are performed and the phase diagrams are constructed. It is shown that the
