Welcome to PF. What experience do you have so far running simulations in Ansys Fluent?Vin B said:I need to simulate mach reflection with mach stem generation using on Ansys Fluent. The wedge angle is of 22deg at Mach 5.
Thank you! I have a basic understanding. Nothing in depthberkeman said:Welcome to PF. What experience do you have so far running simulations in Ansys Fluent?
I fail to understand how you can simulate Mach reflection in a subsonic flow. But otherwise I agree, @Vin B needs to walk before attempting to run.berkeman said:You may want to simulate sub-sonic flow and reflection before trying to tackle supersonic flow. Have you run any sub-sonic simulations yet? What class is this for, and what year are you in university?
Mach reflection is a phenomenon that occurs when a shock wave reflects off a solid surface and creates a secondary shock wave. This can be simulated using computational fluid dynamics (CFD) software, such as Ansys Fluent, by solving the governing equations of fluid flow and accounting for the shock wave behavior.
Mach stem generation is the formation of a strong shock wave at the intersection of the primary and reflected shock waves. It is important in simulating mach reflection because it significantly affects the flow patterns and pressure distribution, and can lead to changes in the overall behavior of the shock wave.
Ansys Fluent uses a variety of numerical methods, such as shock-capturing schemes and adaptive mesh refinement, to accurately capture the complex flow behavior involved in mach reflection with mach stem generation. It also has the capability to model both compressible and incompressible flows, which is crucial in simulating this phenomenon.
Some important factors to consider include the initial conditions, such as the incoming flow velocity and angle, the geometry and material properties of the solid surface, and the boundary conditions. It is also important to carefully select the appropriate turbulence model and mesh settings to ensure accurate results.
Simulating mach reflection with mach stem generation can have various applications in aerospace engineering, such as in the design and analysis of supersonic aircraft and missiles. It can also be used to study the effects of shock waves on structures and to improve the understanding of shock wave interactions in different flow scenarios.
