Monitoring of Argon plasma in a coating manufacturing process by utilising IR imaging techniques Thermal Recordings (NPZ 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.These files are the temperature exported at an emissivity of 0.74, the emissivity of the tool head. These are the corresponding files for the recordings in the collection <b>Thermal Camera Recordings (CSQ Files).</b>File FormatThe files are in NPZ format and can be loaded into Python using the np.load method. The array shape NxHxW where N is the number of frames, H is height and W is width.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.
