Fluid flow over the forward-facing step causes the separation, recirculation, and reattachment phenomena. Experiments are conducted on the forward-facing step of variable step inclinations of 300, 600 and 900 with the fluid flow velocity of 30 m/s. Step heights of 20 mm and 40 mm and a length ratio of 2 are considered for the model preparation. The experimental results observed that the decline in step inclination produces streamline flow on the surface and affects the strength of the recirculation zones. The increase of step height and lower step inclination affect the flow characteristics, considered as favourable insights for prediction of flow behaviour. The observed results have become beneficial in the design of aircraft surfaces, open channels, microfluidic devices and microchannel cooling.
