This reading explores a unique experimental facility. The facility enables the investigation of injection and combustion processes in relation to two-stroke marine diesel engines at relevant physical dimensions and operational parameters, including flow characteristics and low fuel qualities involved. The core element is a disk-shaped optical accessible constant volume spray combustion chamber of diameter 500 mm with peripheral injection into a swirl flow. Kai Herrmann will explain how conditions at the start of injection similar to those in real engines (up to 13 MPa, 930 K) are achieved and how the application of non-intrusive optical measurement techniques contributes to a better understanding of the underlying phenomena and the validation of simulation models.

- Reference Data Generation of Spray Characteristics in relation to large 2-stroke marine diesel engines using a novel spray combustion cahmber concept

- A spray combustions chamber facility for investigations in relation to large 2-stroke marine diesel engine combustion system optimisation

- Investigation of marine diesel ignition and cobustion at egine-like conditions by means of OH* Chemiluminescence and shoot incandescence

- Numerical analysis and statistical description of the primary breakup in fuel nozzles of large two stroke engines for the application in CFD engine simulations
