The vehicle\u2019s aerodynamic drag reduces with lower<br>operating pressures, blockage ratios, and flow Mach number. Most of the publications addressed and<br>studied the blocked model. However, the role of flow ingestion is not well studied. This paper analyzed<br>the ingestion effect on the flow field, power, and drag using multi-dimensional analysis utilizing the<br>Method of Characteristics (1-D) and Unsteady Reynolds Averaged Navier Stokes (URANS) with \ud835\udc58 \u2212 \ud835\udf14<br>SST turbulence model for the 2-D and 3-D numerical models. A comparison between the blocked and<br>ingested models was performed for various ranges of Mach number (0.3 to 0.8) and blockage ratios<br>(0.3 to 0.7) to assess the performance of a wide range of design spaces. The attained results have<br>shown a significant reduction of piston effect, elimination of chocking condition, and providing the<br>required thrust levels to propel the vehicle along the tube. Interestingly, the analysis revealed a power<br>savings of approximately 90% when ingestion was employed with a vehicle speed corresponding to<br>M=0.6 at an operating pressure of 10 kPa.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-386.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-386.pdf\">Read the full paper > <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mohammed Mahdi Abdulla, Seraj Alzhrani, Khalid A.
