2 What’s next for Spray G? Continued work with the data already acquired  Boundary condition verifications  Qualification of data contributions  ESRF geometric data analysis More measurements  X-ray PC imaging - moving needle, cavitation, etc  vapor fuel concentration  combustion? More operating conditions  throttled early injection – flash boiling  unthrottled early injection – still relevant and easy for everybody  small quantity multiple injection?
