| Summary: | Study of 2-D cavity flow becomes more popular among Engineering and Science researchers. Flow investigation using experimental and analytical method, numerical methods and software (Ansys Fluent) to study the physical properties of the flow inside the cavity are very common. For computation simplicity, 2D laminar incompressible viscous fluid flow is assumed. It is further assumed that the fluid is uniformly filled the cavity and he walls are at uniform temperature. The working fluid is air and it shall be assumed as idle gas and other mechanical and thermal properties of fluid are constant with respect to temperature and pressure. Cavity walls such as inner radial (lower curve) and side walls are kept in stationary, while outer-radial boundary is in circumferential movement. The dimensionless radius, R kept as a constant, while Reynolds numbers, Re and polar cavity angles, ? varies. The fluid motion phenomena are studied using Fluent software. The study is focused to discover the flow of physicals properties in different Reynolds numbers and different angles (30°, 60° and 90°). The flow in polar cavity is expected to change dramatically as angles and Re are varied. |
