Axial Flow Compressors and Fans
Published in Ahmed F. El-Sayed, Aircraft Propulsion and Gas Turbine Engines, 2017
The compressor map of an axial compressor is shown in Figure 13.50. It may be noticed that, for a fixed value of N/T01, the range of the mass flow rate is narrower than that in a centrifugal compressor. At high rotational speed, the lines become very steep and ultimately may be vertical.
Surge Control Centrifugal/Axial Compressors
Published in Tony Giampaolo, Compressor Handbook, 2020
Based on a compressor map the surge point is at the following conditions: q = 1220 acfm, flow in actual cubic feet per minuteDischarge Pressure (Pd) = 338 psiaSuction Pressure (Ps) = 118.7 psia

Turbo charger map is chart for determining the compressor efficiency and the map is given in (Figure 3). In the compressor map the horizontal axis represents mass flow rate and the vertical axis represents pressure ratio. Colours in the map represent the efficiency of compressor and the details of Valve timing of Turbo Charger Inter Cooler Diesel Engine in (Table 3).

Uncertainties of inputs to the compressor map—compressor suction and discharge dew point temperature—propagate to the map output and form the uncertainty due to inputs. According to the JCGM GUM 100–2008 (JCGM 2008), the low-order uncertainty due to inputs can be calculated by Equation (14).
