Design Approach:

The fluid flow (movement of air) considered to be Incompressible in the CFD model since there is no significant variation in the fluid density with respect to time within a fluid parcel when it is in motion. To build a mathematical representation of a 3D model and numerically solve the 3D Navier-stokes equations over a discretized flow field, the k-ω SST turbulence model is used for simulating the turbulence behavior of the flow.

Conclusion:

The velocity profiles in the generator room are properly distributed and the temperature till the height of generators in most of the regions is within the permissible temperature rise of 10 ºC and the Power house ventilation system is sufficient to maintain the design temperature conditions for the provided heat loads of generators.
