The Combustion TCP currently engages in seven collaborative tasks which are multi-nation thematic tasks. Each collaborative task has a well-defined scope and formulated research areas which are of interest for the task. The technical leader of the task facilitates and coordinates collaboration of different research institutes, the exchange of researchers, the involvement of new research groups. Each task provides a platform for discussion and exchange of research results as well as the definition of new research areas within the task. Tasks are periodically reviewed for continuation and new task areas to enhance the Combustion TCP efforts are continually being explored.
