FLOW APPARATUS FOR HEAT CAPACITY OF LIQUIDS AND GASES:RESEULTS OF DIMETHYL ETHER
A flow apparatus of calorimeter for measuring isotonic heat capacities of liquids and gases was developed at the pressure up to 25 MPa and temperature from 290 K to 600 K. The apparatus was verified by measuring specific heat capacities of carbon dioxide and nitrogen. The isobaric heat capacities of carbon dioxide at temperature of 302.74-343.19 K and pressure of 0.15-0.35 MPa were measured with 2.99％ difference from literature values. The isobaric heat capacities of nitrogen were measured at 293.26 K-313.06 K and 0.15 MPa-0.55 MPa with 2.37％ difference from literature values. So the reliability of the experimental apparatus was verified. The heat capacities of dimethyl ether (DME) were also measured for the application of alternative fuels.
