.Annex60.Fluid.Movers.Validation.SpeedControlled_y_linear

Information

This example demonstrates and tests the use of a flow machine whose speed is reduced to zero. In the top model, the pressure drop across the pump is constant, and in the bottom model, the mass flow rate across the pump is constant. In the top model, a small flow resistance has been added since a pump with zero speed cannot produce a non-zero pressure raise. For this operating region, the pressure drop ensures that the model is non-singular.

The fans have been configured as steady-state models. This ensures that the actual speed is equal to the input signal.
