AcuSolve Validation Manual
Collection of AcuSolve simulation cases for which results are compared against analytical or experimental results to demonstrate the accuracy of AcuSolve results.
- Turbulent Flow
  This section includes validation cases containing flow conditions that will cause turbulence to form, requiring that a turbulence model is used.
- Steady Flow
  This section includes validation cases that consider steady state flow simulations.
- Laminar Flow
  This section includes validation cases that do not require a turbulence model to be used.
- Internal Flow
  This section includes validation cases that consider wall bounded simulation domains with internally constrained fluid medium.
- External Flow
  This section includes validation cases that consider unbounded simulation domains where external flow is present over solid bodies, leading to free boundary layer development.
- Transitional Flow
  This section includes validation cases containing conditions producing laminar to turbulent flow that are simulated with a turbulence transition model.
- Transient Flow
  This section includes validation cases that consider time dependent flow simulations.
- Heat Transfer/Radiation
  This section includes validation cases that consider the temperature of the flow by simulating one or modes of heat transfer.
- Moving Mesh
  This section includes validation cases that consider time dependent motion within the domain, requiring that the mesh movement be modeled with a differential equation, a fully defined mesh motion or by interpolated mesh motion.
- Reference Frame
  This section includes validation cases that consider multiple reference frame simulations to model the effects of simplified rotational motion.
  - Flow Between Concentric Cylinders
    In this application, AcuSolve is used to simulate the flow of water between concentric cylinders. The outer cylinder is held stationary while the inner cylinder rotates with a constant speed. AcuSolve results are compared with analytical results as described in White (1991). The close agreement of AcuSolve results with analytical results validates the ability of AcuSolve to model cases containing thin annular gaps with flow induced by rotating walls.
  - Flow Inside a Rotating Cavity
    In this application, AcuSolve is used to simulate the flow of air in an enclosed cylindrical cavity with a rotating top and a fixed bottom. AcuSolve results are compared with experimental data adapted from Michelsen (1986). The close agreement of AcuSolve results with experimental data validates the ability of AcuSolve to model cases containing enclosed cavities with flow induced by rotating walls.
- Multiphase
  This section includes validation cases that consider the immiscible multiphase interaction of two fluids.
- Compressible
  This section includes validation cases that consider the compressibility of the fluid using a variable material model.
