### 11.3.1. Setup for Simulations of Fans and Blowers

Fans and blowers behave like liquid pumps, and require a similar model setup. The flow is generally modeled as incompressible and isothermal. The fluid is typically air as a general fluid or as an ideal gas at a specified temperature. The or SST model is used to model turbulence.

Boundary conditions, turbulence models and choice of timestep are the same as for liquid pumps and turbines.
