ESR1 - Experimental investigation of Constant Volume Combustion and its reduced order model (Choomanee Runnoo, ENSMA)
Comprehensive ignition tests on the CV2 Constant Volume Combustion vessel at ENSMA were carried out. Example of fully premixed propane test in figure 2.
ESR2 - Numerical analysis of the interaction between a Rotating Detonation Combustor and an axial turbine (Gregory Uhl, SAFRAN)
Verification by the means of high-fidelity CFD how an exhaust ejector is capable of considerably reducing the total pressure fluctuations stemming from an RDC exhaust, a promising result for turbine integration (see figure 3).
ESR3 - Simulation of CVC combustor (Nicola Detomaso, CERFACS)
A wide set of LES calculations of the ENSMA CV2 combustor have been carried out using AVBP code linked to an ad-hoc developed reduced 2-step mechanism for propane. A good agreement with experiments was achieved (see figure 4).
ESR4 - Experimental characterization of ignition events in CVC like conditions (Maria Clara De Jesus Vieira, ENSMA)
A modified design of the TUMBLE combustor at ENSMA was realized to improve the control of turbulence intensities so as to optimize the ignition sequences. Figure 5 reports an example of measured MIE versus normalized turbulence intensity
ESR5 - Control and impact of RDC wave direction (Provence Barnouin, TUB)
Final outcome is the analysis of the propagation and interaction mechanisms of counter-rotating waves in RDCs with one-dimensional gas dynamics model to capture their dynamics (Figure 6)

Investigation of the role of fuel-air mixing on RDc performance by the means of LES (Figure 7 example of results)
ESR7 - Experimental investigation of rotating detonation combustors including ignition processes and turbine-integration effects (Hongyi Wei, TUB)
Main outcome is the observation of the effect of combustor outlet restriction on the behaviour of the RDC (see Figure 8).
ESR8 - Computational aeroacoustics of the exhaust flow for noise assessment and control (Thomas Golliard, KTH)
Computational aeroacoustics calculations of the RDC exhaust plume and radiated noise were carried out for relevant operating conditions (see Figure 9).

Design and LES CFD modelling of film cooling process in a RDC combustor (see computational grid and results in Figure 11)
ESR11 - Experimental study of cooling solutions for PGC concepts (Umberto Sandri, UNIFI)
Main ol was the experimental investigation of film cooling effectiveness with supersonic flow representative of RDC (see Schieleren measures in Figure 12)
ESR12 - Unsteady numerical simulation of the interaction between pressure-gain combustors and high-pressure turbine stages (Panagiotis Gallis, POLITO)
On of the main goal was the CFD study to develop a transition piece geometry for the CVC combustor available at ENSMA (Figure 13)
ESR13 - Power plant analysis and cycle thermo-economic optimization (Abhishek Dubey, UNIGE)
A complete thermodynamic analysis of gas turbine cycle with a CVC combustor was carried out with WTEMP code (Figure 14a)
