Projekt vychází z předcházejícího experimentálního výzkumu prováděného v Laboratoři přenosu tepla a proudění. Na pracovišti jsou dlouhodobě studovány chladicí účinky proudu kapaliny při dopadu na horký povrch. Díky systematickému vývoji experimentální metodiky a rozvoji invertních úloh bylo popsáno mnoho parametrů ovlivňujících jak chladicí, tak i abrazivní účinky proudu kapaliny.
