RDE-72: Rotating Detonation Engine Spatiotemporal Dataset

Overview

RDE-72 is the first open dataset of full 2D spatial fields from Rotating Detonation Engine (RDE) CFD simulations. It combines 12 high-fidelity OpenFOAM reactingFoam cases with 60 synthetic cases generated via a Conditional Variational Autoencoder (CVAE), enabling neural surrogate modeling and operating envelope mapping.

Key feature: Unlike prior RDE datasets that provide only bulk statistics (mean pressure, temperature), RDE-72 contains complete 2D field sequences showing detonation wave structure, shock fronts, and reaction zones.

Dataset Specifications

Data Structure

import numpy as np

data = np.load('rde_full_dataset_72cases.npz')
fields = data['fields']        # (72, 20, 6, 150, 300)
is_synthetic = data['is_synthetic']  # bool[72], False=real, True=synthetic
