Flow visualization is a fundamental topic in scientific visualization and has been the subject of active research for a long time. Usually, information begins from numerical simulations, for example, those of computational fluid dynamics, and should be investigated by methods for perception to acquire a comprehension of the flow. With the rapid rise of computational power for simulations, the interest in further developed visualization strategies has thrived. The idea is to attain advanced visualization through the means of projection mapping. When incorporated with the properties of the fluid, whose flow is to be studied, we can create a visual simulation by extracting the real-time variations data through sensors and feed it to the projector, which results in a visualization method in the 3D plane. The complete process is made visible as the image is projected through light and also in space. Real-time Flow Visualization using Projection Mapping methods will help attain the same results as the conventional methods at less cost. As this process is crucial for many industries in the testing and design sectors, the desired output must be obtained within the given time constraint. This method will help to optimize the complete process. The result can be used to derive the necessary conditions for the best design and performance of the object or vehicle.
