[EN] State of the art techniques for reducing pollutant emission in internal combustion engines often require local
flow assessment, specially in the air management field. This work addresses the interaction between a ...
[EN] Bulk flow condensation caused by the mixing of air streams at different temperatures and humidities is a thermodynamic process that requires strong assumptions to be calculated with low computational effort. The ...
[EN] A test bench has been designed to assess condensation formation produced on the interior of a low-pressure exhaust gas recirculation cooler working with hot stream of humid air representing an engine warm-up stage, ...
