Supercritical Carbon Dioxide Heat Transfer Data for 0.75 mm Square Microchannels with Horizontal, Single-Side Heated Boundary Condition at Reduced Pressure from 1.03 to 1.1

The attached heat transfer dataset was obtained at Oregon State University in the Thermal Energy Systems and Transport (TEST) Laboratory. Six different testing conditions were investigated with a total of 70 data points, varying the 1.) reduced pressure (P/P_crit of 1.03 and 1.1), 2.) mass flux (500 and 1000 kg m^-2 s^-1), 3.) inlet temperature (T_in = 16 ^oC to 50 ^oC), and 4.) applied heat flux (q" = 20 and 40 W cm^-2). The applied heat flux is on the bottom surface of a horizontal test section with a heated length of 20 mm, more dimension details can be found in the attached dataset and the reference.<br>This attached dataset contains both the measured experimental variables and calculated quantities. The wall temperatures, heat transfer coefficient, and corresponding uncertainty were evaluated using an integrated 2-D and 3-D modeling approach, described in the cited references. Some key details about the data are as follows:1. The values for each measured variable represent the average values of the raw data points (approx. 600) that were directly measured by various sensors.2. The attached file has 6 individual sheets which correspond to the 6 test cases considered in the current investigation.3. The attached file contains a detailed key which can be used to interpret the data set presented in each individual sheet. The sheets are named as, XX-YY-ZZ which represents the experimental conditions for the particular data set.• XX represents the reduced pressure• YY represents the mass flux in kg m^-2 s^-1• ZZ represents the measured heat flux at the flux meter location in W cm^-2<br><br>
