In turbine inlet cooler the evaporation process is enhanced by using a wetted media, usually a cellulose-based honeycomb structure that enables the air to pass through with minimum pressure loss. The media contains internal channels, one for water and one for air, which minimize any water carry-over.
Each turbine in a gas turbine engine has an operating map. Complete maps are either based on turbine rig test results or are predicted by a special computer program. Alternatively the map of a similar turbine can be suitably scaled.
Turbine Meters have a spinning rotor with propeller-like blades mounted on bearings in a housing. The rotor spins as water or other fluid passes over it. The flowrate is proportional to the rotational speed of the rotor. They are used to detect the rotor speed, including mechanical shafts and electronic sensors. They infer the volume by measuring the rotation speed of a turbine suspended in the flow stream. They differ according to the design of the spinning rotor. This can be used on both liquids and gases. They are sensitive to viscosity and low-viscosity fluids
