description: Â  Â  Â  Â  Â  The purpose of this work is to investigate the influence of the inclination angle of the cavitys rear wall in an incoming subsonic compressible gas flow on the oscillation frequency and, as a consequence, to reduce aerodynamic noise. Â  Â  Â  Â  Â  Main stages of the work: 1. Literature review 2. Creation of the computational model 3. Preliminary methodological calculations using the ANSYS FLUENT software package. The methodological calculations will include a study of grid convergence, investigation of the influence of the time step, etc. 4. Conducting a parametric study of the influence of the rear wall inclination angle of the cavity on the frequency and amplitude of self-oscillations. As a result, the influence of the rear wall angle of the cavity on the flow structure was investigated. Based on the conducted studies, it was found that the rear wall angles significantly affect the velocity distribution and the formation of vortex structures within the cavity. The rear wall angles in the range of 60Â° to 130Â° showed both positive and negative effects on the external flow, allowing for the optimization of cavity designs for flow control. The application area of the thesis results includes aerodynamic studies in the aviation and automotive industries, where it is important to consider the impact of geometry on flow characteristics to enhance efficiency and safety.
