This is the data used for the results in the paper "Ignition and combustion study of premixed ammonia using GDI pilot injection in CI engine" (Førby et al, 2022, Fuel). https://doi.org/10.1016/j.fuel.2022.125768

Experiments: In the experiments, premixed ammonia was ignited using a pilot fuel in a CI-engine. The pilot fuel was injected with a GDI nozzle. Very small pilot fuel sprays were used succesfully to ignite the ammonia.

The data available here is the in-cylinder pressure pick-up traces -- collected with LabView-software -- and overviews of the corresponding test conditions.

The data can be loaded and used with Open-Source software freely available through e.g. Python.

Please consult the ReadMe-file for using the data.

This archive contains data files from spark-ignited homogenous combustion internal combustion engine experiments. Included are two-dimensional two-component velocity fields from various measurement planes with maximized field of view, in-cylinder pressure measurements, external pressure and temperature data, as well as details on the geometry of the optical engine to enable setups of simulation configurations. Fired operation was with stoichiometric propane air, 40kPa MAP, at 1300 RPM.

This is a dataset for the 25% scale DrivAer model. Data was collected in the Large Wind Tunnel at Loughborough University, a 2.5m^2, closed working section, fixed ground open return tunnel.The CAD geometry for the mounting hardware and the wind tunnel are all included in the dataset as ASCII .stl files, with the units in m. The CAD geometry of the DrivAer model has not been duplicated for this dataset.Photos of the set up and some unique model dimensions are also included. The model was supplied by FKFS and is a 25% scale DrivAer model with three backs, the estate, fast and notchback variants. The model included the 5 spoke wheels, complex underbody, wing mirrors, the drivetrain, an open front grill and a porous radiator. As the model is not symmetric, in the engine bay and on the underside, it was set at a geometric 0 yaw condition as measured in the wind tunnel. This is estimated to be +/-0.1 degrees.No corrections (for example blockage) have been applied to the data. All the data is presented in SI units and all measurements are from the origin (mid-track, mid-wheelbase on the tunnel floor) with x positive downstream and z positive up, using the right hand rule to find positive y.The data is split into '_Mean' and '_Instantaneous' for each measurement type (Force, Pressure, Flow Field). All the data was taken during the same test session with a total sample time of 300 seconds typically and 100 seconds for the measurements in the stagnation region. The different data sets are not correlated with each other in time. The Force data was sampled at 300Hz, Pressure data at 260Hz and the Flow Field data at 5Hz. The data presented in the '_Mean' folders is the arithmetic mean of that presented in the '_Instantaneous' folders. All the '_Mean' folders contain Comma Separated Variable (csv) files, for ease of parsing with your desired programming language, and the same data is provided in a .dat file that is set up to be read into TecPlot. The csv format was used to reduce size and complexity for the '_Instantaneous' data. Example MATLAB code has been provided (tested in 2018a) that reads both the '_Mean' and '_Instantaneous' csv files for the pressure and flow field measurements, plotting them accordingly.

This archive contains data files from spark-ignited homogeneous combustion internal combustion engine experiments. Included are high-resolution two-dimensional two-component velocity fields acquired at two 5 x 6 mm regions, one near the head and one near the piston. Crank angle resolved heat flux measurements were made at a third location in the head. The engine was operated at 40 kPa, 500 and 1300 RPM, motor and fired. Included are in-cylinder pressure measurements, external pressure and temperature data, as well as details on the geometry of the optical engine to enable setups of simulation configurations.

The associated project aims to understand how acoustic loads are generated in supersonic combustion ramjets (scramjets) to control sonic fatigue in reusable hypersonic vehicles.

This knowledge promises to revolutionise flight by making space access more affordable than it is today. In this project, three aspects of flow phenomena commonly encountered in scramjet engines are being studied – shock/turbulence interaction, fuel injection in a cold supersonic cross-stream and shock/boundary layer interaction for both rigid and compliant surfaces. The intended outcomes include a better understanding of the processes above and construction of an experimental database to validate predictive simulation models that will enable the design of flight-weight reusable hypersonic vehicles. Benefits include reduced cost for access to space and the ability to design and develop advanced aerospace technology.
