I’m trying to understand compressor surge. My basic understanding is that when the pressure behind the compressor drops to below the outside pressure, it will cause air to travel the opposite ...

graphs that assist us in compressor sizing by providing efficiency, surge limit, boost potential and shaft speed data. But before we look at these maps or arrive at an ideal efficiency zone ...

Both are technically compressor surge, and both sound essentially the same, however the different conditions under which they occur are important to identify.
