Raw data from experiment on heat transfer, pressure drop and flow patterns of R1233zde(E) condensing inside horizontal 3 mm channel

Data contains raw measurements of heat transfer coefficient during condensation and raw phots of two phase flow done by high speed camera Photron UX100.
Structure of xlm file: average values are at the top and raw measurements are below. Data is captured by National Instruments DAQ. Some values were typed manually, from apparatus which could not be connected to DAQ.  Average data form previous measurement is kept at the top of the file. Raw data is from the last collected average measurement. Name of phots contain reduced pressure, mass velocity and applied power – this way they should be connected with corresponding measurements. Number of photos added to dataset is limited to fit file size constrains.
