Design optimization of a multi row disk inlet device with an optimum nose cone angle

The inlet is designed to compress the air and increase static pressure. In present work, analyses have been carried out using 2D axisymmetric Reynolds averaged Navier Stokes equations (RANS) capture flow physics of shock structure produced by multi-row disk device at different semi-cone angles. work involves numerical studies on over disk. Drag coefficient, pressure variation, vortex behavior with separation layers observed various angles 12°, 15°, 20° steady-state condition zero attack. At free stream Mach number 2 turbulence model k-o SST, simulations commercial software. Compression through cavity drag coefficient analysis shows better trade-off performance than others. We also obtained that maximum angle for current set-up operating conditions.
