Pressure Drop and Flow Uniformity Analysis of a Complete Exhaust System for Diesel Engines

Pressure Drop and Flow Uniformity Analysis of a Complete Exhaust System for Diesel Engines

BERGEL, André; DUQUE, Edson L.

Artigo:

This analysis takes into account the complete exhaust system (turbo, DOC, DPF, SCR, Muffler, mixers and pipes) to evaluate pressure drop and flow uniformity. This procedure can guide us in order to: identify the most restricting flow element, improving geometry layout of these elements, improving the uniformity of the flow, to reduce velocity at minimum possible value inside each element, improving residence time and conversion efficiencies. It was used real conditions of load for engine exhaust gas flow, temperature, turbine rotation, etc.
