“…CFD studies of store releases are rare, and few use a time accurate approach [10,11,12,13], coupling CFD with a 6DoF method to compute the models trajectory. Kim et al [14] computed releases using k − ω SST and DES from an ideal cavity at Mach 0.95.…”

“…Nevertheless, this work considered a real aircraft and store, the geometrical complexity of which exceeded by far the available generic cases. A sequel of the latter work was presented by Sickles et al 20 In general, when compared to the flight-test data, more time-accurate results for the trajectory were obtained. That can be attributed to the finer used mesh (46 million vs 24.4 million) and/or the number of the overset grid assembly (at each time step vs each 5-10 time steps).…”

In this work, the ability of open-source CFD tools to conduct store separation simulations from cavities is evaluated and validated using a generic test case from the literature. Firstly, the ability and accuracy of these tools for solving cavity flows at high speeds are evaluated. Secondly, their competence in predicting the trajectory of a generic store from a generic deep cavity is checked. Finally, and in order to reduce the associated computational costs, a release-time dependability factor from the recent literature is studied and evaluated. The obtained results using the selected open-source CFD tools matched quite well with the wind tunnel results. Furthermore, the results show that predicting the release-time dependability using a quantified index/factor can be a potential remedy for reducing the computational cost for this type of CFD simulations.
