In this paper, the theoretical study on laminar boundary-layer flow of ferrofluid with influences magnetic field and thermal radiation is investigated. The viscosity over a solid sphere surface examined theoretically for magnetite volume fraction by using equations. governing equations are derived applied non-similarity transformation then solved numerically utilizing Keller-box method. It foun...

The separated flow around a rotating circular cylinder is investigated by the discrete vortex method combined with the boundary layer theory. The Keller Box method is used to solve the laminar boundary layer in order to determine the separation points on the upper and the lower sides of the rotating circular cylinder. The nascent vortices are then introduced near the separation points. A discre...

Global electromagnetic gyrokinetic simulations show the existence of near threshold conditions for both a high-n kinetic ballooning mode (KBM) and an intermediate-n kinetic version of peeling-ballooning mode (KPBM) in the edge pedestal of two DIII-D H-mode discharges. When the magnetic shear is reduced in a narrow region of steep pressure gradient, the KPBM is significantly stabilized, while th...

A study is reported on the value of a modified KBM prosthesis compared with other types of prostheses. Recently a new type of below-knee prosthesis (the so called modified KBM prosthesis) was introduced in the Netherlands. This prosthesis is now frequently used as a substitute for more conventional types. A study was carried out on the value of this new prosthesis, compared with the more conven...

In this paper, mixed convection of ferrofluid containing magnetite, Fe3O4 with ferroparticles suspended in water at the lower stagnation point on a horizontal circular cylinder is investigated. The partial differential equation which derived from transformation dimensional governing and non-similarity consideration effect magnetohydrodynamic (MHD) are solved numerically by using Keller-box meth...

Infrared spectroscopy studies of 1,3-indanedione (ID) in 16 different pure organic solvents were undertaken to investigate the solvent– solute interactions and to correlate solvent properties, such as the Kirkwood–Bauer–Magat (KBM) equation, the solvent acceptor number (AN) and the linear solvation energy relationships (LSER), using the infrared band shift. The correlations were performed both ...

In this investigation, two different models for coupled asymmetrical oscillators, known as, forced damped Duffing oscillators (FDDOs) are reported. The first model of FDDOs consists a nonlinear oscillator (FDDO) with linear oscillator, while the second is composed FDDOs. Krylov–Bogoliubov–Mitropolsky (KBM) method, carried out analyzing any model. To do that, reduced to decoupled system individu...
