Nasal cavity is one of the organs in the human respiration system. Nasal cavity acts as the air flow passage for human ventilation and respiration. The unique geometry of nasal cavity can change the flow behaviour and the flow pattern of air throughout the nasal cavity. This project use to understand the effect and behaviour of air inside the nasal cavity. The project used three inhale breathing condition which is passive, moderate and active breathing. To get the simulation result, the study use an actual human 3D model of the nasal cavity and been added with several boundary conditions into the Engineering Fluid Dynamic (EFD) software. The mesh size that has been used in this study is 0.001m. Before the simulation and analyse process was started, the actual human 3D model of nasal cavity has been validated. The 3D model been compare with the previous study data to make sure that the data that have obtain are valid to use for further study. The results gained from this study are, the geometry have influence the value of velocity and pressure of air that flow inside the nasal cavity. For passive and moderate breathing the air inside the nasal cavity were at laminar state all the time. For active breathing the first half of the nasal cavity the air was at turbulent state, then for the last half of the nasal cavity the air was in the laminar state
