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. 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,
