Real-time visual thermal analysis of the Argon plasma during thermal spray of titanium (CSQ Files)

DescriptionThis dataset contains the thermal imaging recordings made during the experiments investigating the effect of gas flow rate on the shape of the plasma. The index at the end of the file name denotes the order they were taken. The plasma tool head is positioned on the right of the image with the plasma and powder travelling from the right to the left of the image.File FormatThe recordings are in FLIR's Compressed Sequence File format called CSQ. The recordings were made with the emissivity set to 0.94 as the true emissivity was not known at the time. It is recommended to get FLIRs tools to change the emissivity and observe the effects. CSQ files can be viewed with a free license for FLIR Thermal Studio but a paid license is needed to extract temperature values to make the NPZ files uploaded at https://doi.org/10.15131/shef.data.25335319. The metadata of the files (date, time, recording parameters etc.) can be extracted with a tool called exiftool; a custom class has been written as part of the project for inspecting these files and extracting the raw values. The specification is commonly used in thermal imaging.Process Parameterssheffield_doe_flowrate_gasrate_0001: 30V, 500A, 40 SL/MINsheffield_doe_flowrate_gasrate_0002: 30V, 500A, 40 SL/MINsheffield_doe_flowrate_gasrate_0003: 30V, 500A, 50 SL/MINsheffield_doe_flowrate_gasrate_0004: 30V, 500A, 60 SL/MINsheffield_doe_flowrate_gasrate_0005: 30V, 500A, 70 SL/MINsheffield_doe_flowrate_gasrate_0006: 30V, 500A, 80 SL/MINsheffield_doe_flowrate_gasrate_0007: 30V, 500A, 80 SL/MINsheffield_doe_flowrate_gasrate_0008: 30V, 500A, 80 SL/MINRecording Notessheffield_doe_flowrate_gasrate_0001: First run failed due to camera running out of batterysheffield_doe_flowrate_gasrate_0002: Good runsheffield_doe_flowrate_gasrate_0003: Starts with PULSE material flow rate rather than fixedsheffield_doe_flowrate_gasrate_0004: Powder level running low.
