Computational Fluid Dynamics (CFD) is the process of modeling fluid flows by the numerical solution of the governing partial differential equations or other mathematical equations of motion. The attraction of the subject is twofold. Firstly, the desire to be able to model physical fluid phenomena that cannot be easily simulated or measured with a physical experiment. Secondly, the desire to be able to investigate physical fluid systems more cost effectively and more rapidly than with experimental procedures. With help of CFD we did simulation of Wind-catcher. Wind- catcher is device used for proper ventilation, air conditioning. It is situated at top of house, so that it can catch wind and circulate in the house. There has been less research done in area of Wind-catcher specially modeling & simulation of wind-catcher. In this paper we did case study of Wind-catcher with one partition & Wind-catcher with two partitions, & analyzed it for best design with help of pre-processing software that is ICEM CFD 10.0. Solver & post-processing software was used is FLUENT ANSYS 6.2.
