Khallil}, country = {}, institution = {}, abstract = {In this paper, a numerical simulation of a finned store separating from a wing-pylon configuration has been studied and validated. A dynamic unstructured tetrahedral mesh approach is accomplished by using three grid sizes to numerically solving the discretized three dimensional, inviscid and compressible Euler equations. The method used for computations of separation of an external store assuming quasi-steady flow condition. Computations of quasi-steady flow have been directly coupled to a six degree-offreedom (6DOF) rigid-body motion code to generate store trajectories. The pressure coefficients at four different angular cuts and time histories of various trajectory parameters and wing pressure distribution during the store separation are compared for every grid size with published experimental data. }, journal = {International Journal of Mechanical and Mechatronics Engineering}, volume = {9}, number = {4}, year = {2015}, pages = {637 - 643}, ee = {https://publications.waset.org/pdf/10001199}, url = {https://publications.waset.org/vol/100}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 100, 2015}, }
