The Condensation within a CAC - Thermodynamics Analysis

With more emphasis on developing a better fuel-economic vehicle, applications of charged air cooler (CAC) in turbo charged gas and diesel engine plays an increasing critical role in both aspects of reduction of engine intake manifold temperature level and increase of intake air density. However, there is a limitation on how far charged air can be cooled when it starts to condensate within the charged air cooler (CAC).

In this paper, staring from basic thermodynamics principles, a thermal flow model is developed and explains the physical reasons for the condensation generation inside charged air cooler (CAC) tubes.
