Computational and experimental investigation into subsonic flow around a finned ogive cylinder
Abstract
Experimental and numerical investigation into the flow around an ogive cylinder with fins (missile calibration model) was conducted for Mach 0.6 flow. The computational results were compared to the results of pressure-distribution and force/moments measurements conducted in the T-38 trisonic blowdown wind tunnel of the Military Technical Institute of Serbia. In addition to the pressure distribution along the model, the base pressure was computed and compared to experimental data. Standard pre-processing techniques and a realizable k-epsilon turbulence model with enhanced wall treatment were used in the flow computations. The numerical simulation results achieved with moderate hardware resources were found to be in relatively good agreement with the experiment if high separation in the base region and related issues that CFD analysts are faced with are taken into account.
