Increased system efficiency has been gained by reducing heat exchanger approach temperatures and increased isentropic compressor efficiency
to name a few.
A compressor efficiency
model is needed to determine pressure ratio from [mu].
Choosing non-genuine or third party spares can have a negative impact on compressor efficiency
and energy consumption.
with R-516A appeared to be slightly lower than with R-134a, especially at higher pressure ratios.
In case of isothermal OCAES, liquid piston compressor efficiency
is defined as the ratio of stored energy to work input.
CMCs are a key technology advantage for GEs advanced military engines under development, which are setting propulsion records for compressor efficiency
and operating temperatures.
Furthermore, it is expected in actual use that the pressure raise of the ejector will lower the compression ratio of compressor and improve the compressor efficiency
While the cases with slower ramp rates avoid the regions of lower compressor efficiency
, as well as the high off-optimum power turbine speed at high load, the higher average engine efficiency for the faster ramp rates is better than for the slower ramp rates (Figure 4).
By improving compressor efficiency
and recovering heat energy for heating administration rooms, the green salad and herb producer has saved more than 18,000 [euro] per year since it introduced the Boge compressed air and nitrogen formula.
The compressor efficiency
gain was achieved by advancing the design of the compressor impeller, volute, variable diffuser vanes, inlet guide vanes and controls.
This has a significant impact in reducing high compressor efficiency
and stall margins, in these very low aspect ratio blade passages.
The decrease in screw compressor efficiency
at part load is less severe in lower compression ratio applications.
