Abstract:A experiment apparatus based on the pressure decltion method was constructed, and the preliminary results concerning the carbon dioxide-Water diffusion system at 298.15 K were in reasonable agreement with other report. Then it was used to measure the gas pressure versus time for carbon dioxide-RP-3 aviation fuel system under a temperature range from 283.15 K to 333.15 K. The fitting curve agreed with the experimental data perfectly, the diffusion coefficient values at different temperatures were of magnititude 10-8m2/s. From the experimental result, the relationship between the mass diffusion coefficient and temperature satisfied the Arrhenius rate law. A model of prediction of diffusion coefficient of carbon dioxide in RP-3 aviation fuel was built according to existing data in the experiment. To verify the accuracy of the prediction model, more experiments under the conditions of 253.15, 263.15 K and 273.15 K were conducted. The experiment results matched the fitting equation with accuracy and extensionality. © 2017, Editorial Department of Journal of Aerospace Power. All right reserved.
