+ # Navier-Stokes Simulated Flow Dataset for PINNs
14
+
15
+ ## Welcome to the Dataset!
16
+
17
+ Dive into the dynamic world of fluid flow with the **Navier-Stokes Simulated Flow Dataset for PINNs**! This collection of **10,000 simulated data points** captures the essence of fluid dynamics in a 2D channel, tailored specifically for training **Physics-Informed Neural Networks (PINNs)**. With an even split of **5,000 laminar flow** and **5,000 turbulent flow** points, this dataset is perfect for researchers, data scientists, and students exploring how to model fluid behavior using cutting-edge machine learning techniques. Whether you’re studying smooth laminar flows or chaotic turbulent ones, this dataset offers a compact yet representative resource to power your PINN experiments.
18
+
19
+ ## Context
20
+
21
+ The **Navier-Stokes equations** are the cornerstone of fluid dynamics, describing how fluids move under forces like pressure and viscosity. Solving these equations is a challenge, especially for turbulent flows, where chaos reigns. Traditional numerical solvers, like direct numerical simulation (DNS), are computationally expensive, but PINNs offer a promising alternative by embedding the equations into neural networks. This dataset, inspired by PINN research (e.g., the paper on PINNs for Navier-Stokes), provides simulated flow data to train models that learn the physics of fluids directly from data and equations. It’s a bridge between computational fluid dynamics and machine learning, ideal for advancing research and education.

+ ## Dataset Description
24
+
25
+ ### Content
26
+
27
+ The dataset contains **10,000 rows** of simulated flow data in a 2D channel, evenly divided between **5,000 laminar flow** and **5,000 turbulent flow** points. Each row represents a point in a **spatial-temporal grid** with the following features:
28
+
29
+ - **x**, **y**: Spatial coordinates in the 2D channel (in meters).
30
+ - **t**: Time coordinate (in seconds).
31
+ - **u**, **v**: Velocity components in the x- and y-directions (in m/s, non-zero).
32
+ - **p**: Pressure at the point (in Pa).
33
+ - **u_x**, **u_y**, **u_t**: Spatial (∂u/∂x, ∂u/∂y) and temporal (∂u/∂t) derivatives of u.
34
+ - **v_x**, **v_y**, **v_t**: Spatial (∂v/∂x, ∂v/∂y) and temporal (∂v/∂t) derivatives of v.
35
+ - **p_x**, **p_y**, **p_t**: Spatial (∂p/∂x, ∂p/∂y) and temporal (∂p/∂t) derivatives of p.
36
+ - **flow_type**: Label indicating `laminar` or `turbulent` flow.
37
+
38
+ ### Simulation Details
39
+
40
+ - **Laminar Flow**: Generated using the analytical **Poiseuille flow solution** with added noise to ensure non-zero transverse velocities (v ≠ 0), mimicking realistic detector-like data.
41
+ - **Turbulent Flow**: Created by perturbing Poiseuille flow and evolving it with a basic **Navier-Stokes solver**, incorporating random noise to simulate turbulent behavior.
42
+ - **Purpose**: Designed to provide a balanced, compact dataset for PINN training, with derivatives included to enforce physics constraints in the loss function.
43
+
44
+ ### Format
45
+
46
+ - **File**: Stored as a CSV file (e.g., `navier_stokes_flow.csv`) in the `data/` directory.
47
+ - **Size**: 10,000 rows, with columns for coordinates, velocities, pressure, derivatives, and flow type.
48
+
49
+ ### Source
50
+
51
+ The dataset is synthetically generated to emulate flow data for PINN training, inspired by methodologies in PINN research for solving the Navier-Stokes equations. It is curated for public use, enabling researchers to explore fluid dynamics modeling without access to expensive CFD simulations.
52
+
53
+ ## Use Cases
54
+
55
+ This dataset is a versatile resource for a range of applications:
56
+
57
+ - **PINN Training**: Train Physics-Informed Neural Networks to solve the Navier-Stokes equations for laminar and turbulent flows.
58
+ - **Machine Learning**: Develop models to predict velocity or pressure fields from spatial-temporal coordinates.
59
+ - **Data Visualization**: Create plots of flow fields (e.g., velocity streamlines, pressure contours) to study fluid behavior.
60
+ - **Research**: Investigate the differences between laminar and turbulent flows using ML or analytical methods.
61
+ - **Education**: Use in CFD or machine learning courses to teach PINN concepts and fluid dynamics.
