Jet Engine Simulation Laboratory (JetSim)

• We have developed the zFlare software module for numerical modeling of 3D turbulent flows of viscous multicomponent gases with nonequilibrium combustion within the RANS and LES approaches using multiprocessor computers. The module implements new high-performance computation technologies: the fractional time step method, the law of the wall and others. The turbulent combustion models are also included among which are the newest models EPaSR and GPaSR. RANS and LES computations of high-speed flows with combustion have been compared to data from open databases and experiments conducted by the Central Aerohydrodynamic Institute – TsAGI. We have achieved the world-class level of quality of experiments.

• We have organised «fire» aerodynamics experiments using the Т‑131 high-speed facility of the Central Aerohydrodynamic Institute - TsAGI. The experiments were aimed at validation of the physical models and programs. We have designed and produced an experimental model with four pairs of optical windows for visualisation of the structure of the flow. During the experiment we ensured high-speed shadow video recording of the flow; visualisation of radiation of active particles in the flame region; measurement of wall temperature using thermocouples; registration of time-averaged distributions of static pressure along the walls as well as pressure pulsations measurements. A new Russian database containing results of experiments involving flows with high-speed combustion in channels.

• We have created an «virtual experimental setup» that allows to modernise engines with a resonator and rotating detonation engine for a wide range of critical parameters. Detailed numerical computations on the «Lomonosov» supercomputer have proven the possibility of implementation of rotating detonation, controlling the direction of wave rotation and the characteristics of engines with a resonator and rotating detonation. The Laboratory has conducted a research of fuel combustion using the technology of thermochemical conversion of fuel.

Implemented results of research:

• We have filed three patent applications and registered them on the www.rosrid.ru website («A rig for research of the work process in a direct-flow combustion chamber», «A combustion chamber of a ramjet aircraft engine», «A method of functioning of a detonation engine and a device for its implementation»).

• A certificate of state registration of the zFlare program has been obtained.

• 4 know-hows have been registered («A mathematical model of «catalytic» initiation of chemical reactions», «A method of computation-efficient and stable solving of nonlinear equation systems of a partially stirred reactor (PaSR) model», «A method of elimination of the effect stopping of development of a process in time in computations of turbulent flows using the SST model», «A series of techniques for stabilisation of vortex-resolving computations of flows of multicomponent gases including flows with chemical reactions»).

Education and career development:

• Two doctoral dissertations and two candidate dissertations have been defended.
• Two postgraduate students of the Moscow Institute of Physics and Technology have been recruited to the Laboratory after completing internships
• Head of the Laboratory is the research adviser for a postgraduate student from China PR.
• Employees of the Laboratory teach at the Faculty of Aerodynamics and Aircraft of the Moscow Institute of Physics and Technology (courses in molecular turbulence, gas dynamics and combustion gas dynamics etc.).

Collaborations:

• Laboratory of Plasma Methods Ignition and Combustion Control in High Temperature Flows of the Joint Institute for High Temperatures of the Russian Academy of Sciences (Russia): an application for a Russian Science Foundation grant has been prepared to fund a joint computational and experimental research.

• «Kintech Lab» in Skolkovo (Russia): a collaboration agreement for 2020-2021.
