It sure is great to have this forum back, I love reading the information on here!
Anyway, on to my question: Assuming that pre-impeller injection either moves the entire compressor map to the right, which is what I gather the correct conclusion must be if it pushes the choke line to the right AND moves the surge line to the right, then would the following be a correct statement?:
Pre-impeller injection is a good technique to employ if your turbo is a bit small for your application, but NOT if your turbo is large enough that surge is a concern. In that case, some location post compressor is the better option for the nozzle to be located.
? ? ?
Thanks!
