NUMERICAL PROPULSION LAB
The Numerical Propulsion Lab has a long standing experience in all the various theoretical and numerical analysis tools which guide the design process of rocket engines employing liquid, solid or hybrid propellants.
Such engines/motors are complex systems composed of numerous subsystems each with its own peculiar range of physical phenomena characterizing it, from gasdynamics phenomena, aeroacoustic phenomena, combustion of liquid or solid fuels, multiphase flow effects, to heat exchange to surface erosion to turbulence and real gas effects. When the propulsion system is viewed as an integrated system, multidisciplinary approaches are generally used in order to analyze the interaction of each subsystem.
A wide choice of numerical tools are employed in the Propulsion Lab, including inhouse and commercial/opensource computational fluid dynamics codes, both for compressible steady/unsteady and lowMach number reactive flows, even in complex geometries, which are selectively specialized and enriched with submodels depending on the particular problem. The following is a list of topics currently being investigated in the Numerical Propulsion Lab:
