Abstract

In the present study, the idea of heat-transfer enhancement from a duct wall is based on generating the intensive flow vorticity parallel to a magnetic field downstream of a field-aligned cylinder. The electromagnetic effects on the quasi-two-dimensional flows is in the form of Hartmann friction and the forcing due to the injected electric current from a Hartmann wall. The electric current amplitude and frequency are systematically varied to explore its influences on the convective heat transport phenomenon. This investigation builds on a recommendation from previous work dedicated to understand of the flow stability in a similar configuration. The results indicate that the imposed current injection significantly alters the dynamics behavior of the wake behind a cylinder, and that the convective heat transfer improves by almost twofold.
