2 Objectives To become proficient in using Fluent and Gambit To get experience in:acquiring numerical solutions of PDEsolving a CFD problem
3 Problem DescriptionStudy on the influence of different side wall boundary conditions on flow characteristics in a 3D geometry.- Flow types1. Flow in a rectangular channel Flow over a surface mounted cube- Boundary Conditions1. Periodic Solid
4 Flow GeometryChannel Geometry: 2h in height, 2h in flow direction, and 3h in spanwise direction. (h=0.025m)Channel with surface mounted cube:Fluid: airData from Hussain and Marinuzzi’s experiment (1996) was used.
15 Results and Conclusion We have learned how to use Fluent and Gambit to design simple meshes and solve CFD problems in application to turbulence modeling.Different boundary conditions on side walls have a great influence on the flow characteristics, such as velocity, vorticity, and turbulent kinetic energy.
