De stroomrichting van het gas is langs de as en wordt niet van richting veranderd, waardoor er een hoge efficiëntie bereikt wordt. Centrifugal Compressor Centrifugal Compressors. A centrifugal compressor is a radial flow rotodynamic fluid machine that uses mostly air as the working fluid and utilizes the mechanical energy imparted to the machine from outside to increase the total internal energy of the fluid mainly in the form of increased static pressure head. AXIAL RADIAL COMPRESSOR.

This arrangement of blades creates multiple stages resulting in high efficiency and pressure ratio per casing. Axial compressors are high-speed, large-volume compressors but are smaller and somewhat more efficient than comparable centrifugal compressors. The axial compressor's capital cost is higher than that of a centrifugal but may well be justified by energy cost savings in an overall evaluation. In the centrifugal-flow engine the compressor is between the accessory section and the combustion section; in the axial-flow engine the compressor is between the air inlet duct and the combustion section. *Centrifugal-flow compressors have the following advantages: * High pressure rise per stage. In axial flow compressors the centrifugal effect is minimal because the radial component of velocity is suppressed and the flow is basically quasi-two-dimensional, a function primarily of the axial and azimuthal coordinates z and θ. Thus cr ~ 0 and wr ~ 0 and c = c (z, θ) and w = w (z, θ).

If playback doesn't begin shortly, try restarting your device. Videos you watch may be added to the TV's watch history and influence TV Axial compressor can elaborate a higher flow than the radial, which has a higher pressure ratio per stage, this means that for the same flow rate the firsts will have a smaller diameter, but it will need more stages to reaches the same pressure ratio.
