| Abstract | ||
| This study reveals the increase in heat transfer using passive and active techniques for BFS. Backward- facing step (BFS) flow is one example of a representative model for separation flows which has been noted in its applications in engine flows, vehicles, condensers, heat transfer systems, and flow around structures, aerodynamic flows. To learn about the importance of backward-facing step flow from a theoretical and engineering perspective, this work provides a comprehensive review of heat transfer and flow results of forced convection flow with passive and active techniques in a channel containing flow separation and subsequent reconnection. The objective of the research was to give a synopsis of the effects of several parameters, such as the Prandtl number, Reynolds number, nanoparticle volume fraction, Hartmann number, tilt angle, buoyancy force, and Coriolis force.
