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.
- Species Transport
  This section includes validation cases that consider the mixing of multiple species by modeling the species advection/diffusion equation.
- Multiphase
  This section includes validation cases that consider the immiscible multiphase interaction of two fluids.
  - Multiphase Flow of a 2D Dam Break
    In this application, AcuSolve is used to simulate the collapse of a water column surrounded by air. AcuSolve results are compared with experimental results adapted from Rodriguez and others (2013). The close agreement of AcuSolve results with experimental results validates the ability of AcuSolve to model multiphase flow problems.
  - Multiphase Flow Within a Sloshing Tank
    In this application, AcuSolve is used to simulate water and the time-dependent interface of air-water within a tank subject to a prescribed sloshing motion. AcuSolve results are compared with experimental pressure measurements as reported by Tankaka, et al. (2000) and Rhee (2005). The close agreement of AcuSolve results with experimental results validates the ability of AcuSolve to model multiphase flow problems with user-defined motion.
  - Two-Phase Nucleate Boiling in a Cylindrical Pipe
    In this application, AcuSolve is used to simulate the changes in wall temperature due to two-phase nucleate boiling at the heated walls of a pipe with water flowing through it. AcuSolve results are compared with experimental results adapted from Koncar and others (2015). The close agreement of AcuSolve results with experimental results validates the ability of AcuSolve to model two-phase nucleate boiling problems.
- Compressible
  This section includes validation cases that consider the compressibility of the fluid using a variable material model.
