Rayleigh-Bénard Convection (2D) Dataset
This dataset contains 2D numerical simulations of Rayleigh-Bénard convection using the IncompressibleNavierStokes.jl framework, specifically designed for long-duration analysis of flow reversals.
Physics & Numerical Setup
The simulation models a fluid in a square box heated from the bottom and cooled from the top.
Governing Equations
The system is governed by the incompressible Navier-Stokes equations under the Boussinesq approximation:
- Mass: $$ \nabla \cdot \mathbf{u} = 0 $$
- Momentum: $$\partial_t \mathbf{u} + (\mathbf{u} \cdot \nabla)\mathbf{u} = -\nabla p + Pr \nabla^2 \mathbf{u} + Pr Ra \theta \hat{\mathbf{y}}$$
- Energy: $$\partial_t \theta + (\mathbf{u} \cdot \nabla)\theta = \nabla^2 \theta$$
Data Format
All the files are inside datasets/ folder in zipped format. Each zipped contains simulation with varying Pr and Ra number, which can be identified from the name of file as RB_Ra_Pr.zip
File format inside the zip is *.HDF5, named as sol_{file_idx}_{time}.hdf5. The data inside this files are in format as shown below:
| Dataset Name | Description | Shape |
|---|---|---|
velocity |
Velocity field $\mathbf{u} = (u, v)$ | (258, 258, 2) |
temp |
Temperature deviation field $$\theta$$ | (258, 258) |
pressure |
Kinematic pressure field $$p$$ | (256, 256) |
time |
Non-dimensional simulation time ($$t$$) | Scalar |
Visualization of Data
