This investigation delivers the results of the study in two dimensions of the inuence of the geometry at the entrance of the diuser of a ramjet engine using the ANSYS-Fluent software. Initially, the isentropic, thermal and gas dynamics ow
calculations were performed in order to obtain the ramjet operational parameters;
from these results, dierent geometries at the entrance of the diuser were proposed, which in this particular case has a central core, whose main function is the generation of oblique shock waves in order to make the diusion process gradually without generating great amount of losses. The proposed geometries were simulated through the ANSYS -Fluent software in order to know their inuence on the isentropic ow behavior. Finally, it was possible to verify that the variation of the wedge ang
