Centrifugal compressor influence on condensation due to Long Route-Exhaust Gas Recirculation mixing

摘要: Abstract State of the art techniques for reducing pollutant emission in internal combustion engines often require local flow assessment, specially air management field. This work addresses interaction between a turbocharger compressor and 3-way long-route EGR joint, where exhaust gases are mixed with fresh air. A validated methodology simulation is combined condensation model this work. Numerical simulations two different working points three flap positions conducted. The influence these operating conditions on field evaluated. Particularly, there connection mixing both steams generation water condensates, responsible erosion impeller loss efficiency. Moreover, neglecting impact presence production shown to be low magnitude, so that without regarded as accurate, thus computational effort by orders magnitude.
