A unsteady MHD heat transfer by free convective micropolar fluid flow through an infinite vertical porous medium under the action of strong magnetic field have been studied numerically with induced magnetic field. This investigation is performed for the turbulent boundary layer cooling problem with constant suction velocity. The unconditionally stable implicit finite difference technique is used to solve the non-dimensional momentum, angular momentum, magnetic induction and energy equations. The computed values of fluid velocity, angular velocity, induced magnetic field and temperature distributions as well as the steady-state wall shear stress, wall couple stress, current density and Nusselt number are shown graphically. Finally, the important findings are listed here.

Unsteady MHD heat and mass transfer by free convective micropolar fluid flow over an infinite vertical porous medium under the action of transverse magnetic field with thermal diffusion have been studied numerically in the presence of constant heat source. This investigation is performed for both cooling and heating problem with constant suction velocity when the medium is subjected to constant heat and mass fluxes. A finite difference technique with stability and convergence analysis is used to solve the non-dimensional momentum, angular momentum, energy and concentration equations. The computed values of fluid velocity, angular velocity, temperature and concentration distributions, wall shear stress, wall couple stress, Nusselt number and Sherwood number are shown graphically. Finally, a qualitative comparison with previous work is tabulated.

The steady 2-D convective micropolar boundary layer driven by a pseudoplastic power law fluid on a vertical plate was studied. By using suitable similarity transformation, the governing non-dimensional boundary layer equations are reduced into ordinary differential equations containing three parameters: coupling constant, microrotation parameter and power law exponent. The numerical solution of the resulting problem is obtained using Mathcad. The effects of these parameters are presented graphically as velocity and angular velocity profiles. In addition, the result shows that the parameters have appreciable influence of the flow.

We performed Reverse Monte Carlo analysis (RMCA) to study amorphous structure of a heterofullerene, CN by using pulsed neutron powder diffraction data. The scattering function S(Q) shows that the structure is amorphous, while the atomic pair distribution function (PDF) shows that the local structure is similar to that of C. Obtained structures strongly depend on the initial models. Problems for this RMCA method are discussed.

We performed Reverse Monte Carlo (RMC) simulations to study the amorphous structure of a heterofullerene, C59N. Neutron diffraction data of the powder sample with about 0.7 g were collected for 16 h at room temperature, using the neutron powder diffractometer NPDF [1] at the Manuel Lujan Neutron Scattering Center of Los Alamos National Laboratory. By using fourier transformation of the scattering function S(Q), the atomic pair distribution function (PDF) of the C59N was obtained.
