Simulation and Flow Field Analysis of Objects in Fluids

This project mainly focuses on the investigation of the distribution of the streamlines around an object in a fluid like air or water and verifies the effectiveness of the shape of the objects based on the pressure and drag distribution to reduce drag and energy expenditure. This paper uses the simulation of streamlines to simulate the behavior of the streamlines of a certain fluid and analyzed the curvature and density of the streamlines to study the pressure and drag experienced by certain parts of the objects. This study is mainly divided into two parts: rocket and swimmer. The common result is that it is better for an object to be streamline shaped to minimize drag and save more energy.
