A subset of the WP Core Benchmark CFD Set: Deliverable 1.1., in relation to the European Union's Horizon Europe research and innovation program (HORIZON-CL4-2021-DIGITAL-EMERGING-02-10) under grant agreement No. 101080085 QCFD (https://doi.org/10.3030/101080085).  The dataset covers the raw data of using a finite volume method in the framework of HELYX (engys). In the experiment, the 1D passive scalar transport equation is solved with engineering boundary conditions. Within the symmetric geometry, with a linear variation in the cross-section, the prescribed velocity is set to maintain a constant volume flux within the nozzle. The results cover recordings of the scalar field for every 100 th time instant.
