<div>The following set of data was taken at Oregon State University in the Thermal Energy Systems and Transport (TEST) Laboratory. Six different testing conditions were investigated with a total of 90 data points, varying the 1.) reduced pressure (P/Pcrit of 1.03 and 1.1) 2.) mass flux (500 and 1000 kg/m^2-s)3.) inlet temperature (Tin 20C to 100C) and 4.) applied heat flux (q" 20 and 40 W/cm^2). The applied heat flux is on a single side surface with a length of 20 mm, more dimension details can be found in the attached dataset. </div><div><br></div><div>The data here was evaluated for an average heat transfer coefficient using three local measurements. The images in the attached file can assist with understanding where the testing condition data are measured. The three local flux meter temperatures ([1] - [3]) are average at each of the locations (A and B), which provides an average on the flux meter for evaluating the heat flux, wall temperature, and ultimately the heat transfer coefficient. </div><div><br></div><div>The 'Testing Condition Data' is all of the recorded and average testing data that is used to calculated important quantities. The rest of the sheets are for each of the individual testing cases (see right); the names are broken up in three parts (#_#_#). The first number defines the reduced pressure (PR), the second number describes the mass flux (G), and third number describes the applied heat flux (q").</div><div><br></div><div>For more details regarding the experiments, results, and conclusions, the M.S. thesis for this work can be found at (click on 'view/open'): https://ir.library.oregonstate.edu/xmlui/handle/1957/60592</div><div><br></div><div><br></div>
