The purpose of this investigation was to see what effect, if any, the starting length had on mass transfer from a cone. A blowdown supersonic wind tunnel was utilized to bring about a flow regime of approximately Mach 3.15. The experimental results of mass transfer from cones in supersonic flow are presented and a comparison to theoretical values is made. The cones used in the mass transfer tests were made of copper coated with p-dichlorobenzene. The amount of mass transfer was determined by weighing the cones before and after each test run. The error due to mass lost during transit from the scales to the test section and back was taken into account by later measuring an average mass transfer per unit time due to free convection alone. The results of the mass transfer tests are presented in a plot of mass transfer Colburn j factor as a function of Reynolds number. Author
