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

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.

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.
