Flow visualization has been an important tool in fluid dynamic research which is qualitatively done to measure and anlayze the flow behavior of fluid pattern. Most fluids are hardly visible and their flow is ambiguos where a visual image of the actual flows is needed to picture the characteristic og the fluids. The visualization of the flow can be displayed in several techniques where in this project, smoke-wire technique taken from tracer method is used for visualization in the Curtin University's subsonic wind tunnel.
