Abstract : The project focused on the mixing behavior of fluids under transcritical flow conditions. This topic is relevant to rocket propulsion applications and it is also applicable to other high pressure systems such as gas turbine combustors. Extensive work in this general area of propulsion has been performed at the EM2C (Energetique, Moleculaire, Macroscopique et Combustion) laboratory at Ecole Centrale Paris (ECP) which has suitable complemented the experimental work that has been recently conducted at the Air Force Research Lab at Edwards Air Force Base. The report, which is divided in three major parts, encompasses the results of modeling efforts, further analysis of experimental data, and comparisons between the two. The first part deals with the Large-Eddy Simulation of nonreactive shear coaxial jets, the second part expands on the area of spectral analysis and the final part presents the work performed using an in-house code developed by the Numerical Combustion Group of the EM2C laboratory. This code is based on the Direct Numerical Simulation technique.
