Active chamber cooling systems are often required in liquid rocket engine designs to suitably extract heat from the hot-gas flow and maintain a reasonably low wall temperature. In the design process, numerical simulations are mandatory to reduce the number of expensive hot-firing tests. In this paper, models and their implementation in the EcosimPro/European Space Propulsion System Simulation (ESPSS) framework concerning liquid and gaseous film cooling modelling developed since the ‘50s and available in open literature are briefly presented, paying particular attention to numerical and modelling aspects in liquid rocket engines combustion chambers and nozzles.

Abstract
Active chamber cooling systems are often required in liquid rocket engine designs to suitably extract heat from the hot-gas flow and maintain a reasonably low wall temperature. In the design process, numerical simulations are mandatory to reduce the number of expensive hot-firing tests. In this paper, models and their implementation in the EcosimPro/European Space Propulsion System Simulation (ESPSS) framework concerning liquid and gaseous film cooling modelling developed since the ‘50s and available in open literature are briefly presented, paying particular attention to numerical and modelling aspects in liquid rocket engines combustion chambers and nozzles.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
