PIV IN A RUNNING AUTOMOTIVE ENGINE: SIMULTANEOUS VELOCIMETRY FOR INTAKE MANIFOLD RUNNERS
SINOPSIS
To realize a model of the global automotive engines air loop, CFD simulations can be devised to obtain responses from each part of the air loop. This work addresses an experimental method to validate a CFD model of the intake manifold. Several technical diffi culties appear when one wants to make experimental measurements inside the air loop, especially in a running engine. Such experiments are still quite rare. We make experimental measurements using the particle image velocimetry (PIV) method. An integrated system is designed to achieve PIV measurements in the intake manifolds runners of a real running diesel engine at a representative speed of 1500 rpm and load 40 N·m. Simultaneous velocity measurements are performed in the four tangential runners of the automotive intake manifold. The pairs of PIV images are first pre-processed and then processed by the iterative cross-correlation method. Specifi cally developed for this application, a homemade soft ware assumed the full PIV processing. The results are then compared with the CFD responses and show the successfulness of the CFD model.
