Being able to accurately model and extract information from the cylinder pressure is important for the interpretation and validity of the result. READ MORE

6. 4. Measuring with pressure sensitive paint in time-varying flows

   Author : Markus Pastuhoff; Henrik Henrk Alfredsson; Ulrich Henne; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pressure sensitive paint; fluid mechanics; internal flow; pulsating flow;

   Abstract : Increasingly tougher legislation on internal combustion engine emissions drives the development towards smaller engines with higher efficiency where an important component is the gas-exchange system and especially the turbocharger. The flow in the gas-exchange system is inherently pulsating and unsteady and the present thesis aims at investigating if and how pressure sensitive paint (PSP) can be used for internal unsteady flows of relevance for engine applications.
