Abstract: This paper presents a computational study of the ELECTRE experiments in the HEG facility. A theoretical study of all the 9 shots conuducted in the experiment will be carried out to compare the theoretical heat flux distributions with the experimental values. ANSYS Fluent will then be used to simulate the flow the Electre model, which is a spherically capped blunted cone. The results are then compared with both the experimental and theoretical values. In this paper, the Dunn-Kang model was used to model a five-species reacting flow. The heat capacities of the five individual species were updated with the more recent seven-coefficient Gordon-McBride equation for a higher applicable flow temperature. The kinetic theory model was used to model the individual gas species transport properties, and the ideal gas mixing law was used to model the resultant gas mixture. With the current setup, coupled with a proper mesh, Fluent was able to compute accurate heat flux distributions for the Electre model.
