Abstract

A case study of flow over a body of revolution was done in order to understand the variation of flow parameters past the projectile and performance of the computational code. The pre-processor software ANSYS ICEM-CFD and ANSYS FLUENT 14.5 were used to model 155mm M107 artillery projectile which has been built in INVENTOR software. The flow over projectile was solved as three-dimensional flow in which angle of attack can be considered in the calculations. Aerodynamic forces and moments are computed with the computational fluid dynamic solver. A modified point mass simulation flight dynamics model is applied for the accurate prediction of trajectory of the projectile via atmospheric flight to final impact point in order to improve its precision.
