Abstract
A turbocharger with a high pressure (HP) and low pressure (LP) stage, designed such that swirl in a conduit providing fluid communication between the LP compressor outlet and the HP compressor inlet is received by the second stage compressor counter to the direction of rotation of the second stage compressor wheel. This is achieved without requiring vanes such as inlet guide vanes, and thus is highly efficient as well as free of blockage and excitation.
