Supercritical Carbon Dioxide Heat Transfer Data for Rectangular Microchannels and Micro-Pin Array with Non-Uniform Heated Boundary Condition at Reduced Pressure of 1.1

The attached data were obtained at Oregon State University in the Thermal Energy Systems and Transport (TEST) Laboratory. The experiments were conducted using the supercritical facility with 99.5% (food grade) carbon dioxide (CO2). A range of conditions were investigated with a total of 113 data points collected. The experimental variables included 1) channel flow geometry 2.) mass flux (G) 3.) inlet temperature (Tin) 4.) applied heat flux (q") and 5.) orientation of the test section (Top and Bottom heating boundary condition). The heat flux is applied on a single side surface of the flow channels, designated as the directly heated length shown in Figure 1. The convention adopted for the flux meter thermocouple names is : T X_Y where X is the column number of the thermocouples shown in Figure 1. Column 1 is closest to the position where the development length ends and Column 3 is where the directly heated length ends. Y is the row of the thermocouples. The row closest to the heated wall is numbered as 1 and the row immediately below is numbered 2. <br>Summaries of the measured and calculated values that are included in the paper are presented in the remaining sheets of this document. The names of the sheets follow the convention which consists of five parts (#_#_#_#_#). The first number defines the reduced pressure (PR), the second number describes the mass flux (G), the third number describes the applied heat flux (q"), the fourth variable denotes the channel type (see the key below) and the fifth variable describes the heating boundary condition, i.e. top or bottom heated.
