摘要：

Magnetic convection of air around a hot circular cylinder placed in a square cavity under the influence of an external magnetic field and in absence of gravity is considered. Fluid motion occurs due to the gradients of the magnetic and temperature fields. A collocation meshless method is used for the numerical solution of the governing equations. The results are presented through temperature contours and velocity vectors at steady state. Nusselt numbers are also given for magnetic Rayleigh numbers of 10(5) and 10(6).
