Supersonic Wind Tunnel Design Expert Needed
Budget: $30 – $250 USD
I'm seeking an experienced professional to help with the design of a supersonic wind tunnel. Its purpose is to test an oblique conical shock around a cone-shaped model. The project will cover all aspects from preliminary design to structural analysis and machine design, utilizing CFD with Ansys and 3D modelling.
Key Requirements:
- Expertise in structural analysis and machine design is crucial
- Proficiency in CFD using Ansys
- Advanced skills in 3D modelling
- Strong understanding of aerodynamics and propulsion
- Experience in conceptual design
I need assistance primarily in the simulation, structural and design phase. The project will focus on stress and strain calculations as well as material selection and testing. Your role will not only be to help design the wind tunnel but also to ensure the model can withstand the conditions it will be tested in.
Supersonic Wind Tunnel
Objective: Design a supersonic wind tunnel to test an oblique conical shock around a cone shape model
Procedure: Conceptual Design --> Preliminary Calculation & Sizing --> Nozzle Geometry --> CFD Simulation --> 3D Modelling, Structural Analysis & Machine Design --> 2D Drawing & Manufacturing Process
Conceptual Design:
Choose a pressure supply method: High Pressure Inlet or Vacuum Outlet or Both Method
Choose an operating altitude: Determine Test Section Pressure
Preliminary Calculation & Sizing:
Determine Area Ratio --> Diameter Ratio
Determine Oblique Shock Angle --> Test Section Diameter
Determine Throat Diameter
Determine Inlet Pressure
Choose Outlet Pressure the Roughly Determine Diffuser Throat Diameter
Nozzle Geometry: To avoid a non-uniform expansion and shock wave inside the converging part of a nozzle, method of characteristic shall be used. Ref: Method of Characteristic by JoshTheEngineer https://github.com/jte0419/Rocket_Nozzle_Design
CFD Simulation:
Simulate Inviscid Compressible Flow through Supersonic Wind Tunnel: from nozzle inlet to diffuser outlet
Meshing: Structural Mesh
Method: 2d Axisymmetrical Method
Important Note: Diffuser is also a shock wave holder, therefore, if a shock wave is created before the cone or a strong oblique shock is created, the diameter of the diffuser shall be increased.
3D Modelling, Structural Analysis & Machine Design:
Conceptual Design: Design idea shall be described (e.g. Circular shape tank is employed as a high pressure inlet reservoir and Why it is used??).
Sizing: Dimensions of all components shall be given. These could be determined by an analytical calculation or a structural simulation using FEM software.
Safety Factor: Safety factor in a component design shall be given.
Joints: Type of Joint shall be described for all connection (Permanent or Nonpermanent)
Nonpermanent Joint: Detail of connector type, gasket and fastener shall be given.
3D Model: Model of parts and assembly shall be given.
2D Drawing:
2D drawing of all parts and assembly shall be given as well as a bill of materials (BOM).
Manufacturing method shall be described.
