New high-pressure nitrogen test rig for optical spray characterisation

A new high-pressure nitrogen chamber has been constructed.

The chamber operates with nitrogen in the range of 1 to 80 bar and 15 to 40ºC so that evaporation is not taking place.

Three windows allow proceeding with different optical techniques with Diesel injectors. The chamber itself is constructed with a modular approach allowing the use of different configuration, shadowgraphy, side illumination, two hole or multi-hole nozzles, etc.

The chamber is located in a close loop facility filled with nitrogen; two parallel compressors allow to reach the desired chamber pressure before injection starts. There are two filters to eliminate the fuel from previous injections.

The installation could be used for any type of injectors, not only diesel ones, it maybe possible to visualize plain orifice atomizers or gasoline injectors.
