| Abstract;The ethylene glycol, as one of the representative heat transport fluid, is provided by the Pollutant Release and Transfer Register (PRTR) law, because of its influence for human's DNA. It is anticipated that the development of the heat transport fluid which is not influenced on environment. This paper deals with the heat transport estimation of the saccharide aqueous solution by the thermophysical properties. It were measured that the freezing point depression, density, specific heat and viscosity of the saccharide aqueous solutions. The parameters are concentration of the solutes and the solutions temperature as a liquid phase. The selected solutes are D-mannitol (HOCH2(CHOH)4CH20H), Palatinose Monohydrate (C12H22O11 H2O), D-sorbitol (C6H14O6), Sucrose (C12H22O11) and D-xylose (OCH2(CHOH)3CHOH). The freezing point depression is studied by the theoretical (Raoult's law) and experimental method. The sink-float method is used for measurement of the solution density. The rotaty viscous meter is used for the viscosity measurement of the test solutions. It is selected for the specific heat measurement that the electric heating wire method. The accuracies are freezing point depression .+-.0.1K, density .+-.0.001g/m'3', specific heat .+-.2.8% and viscosity .+-.4.3%. Five type of solutions are used for the evaluation of freezing point depression. As a result, two of the test solutions are picked as the practical heat transport fluid. The estimation of the saccharide aqueous solutions as the heat transport fluid is carried out by the non-dimensional value (heat capacity ratio) and Reynolds number. The obtained useful correlation equations of the thermophysical properties are showed as the function of the concentration and the temperature. (author abst.) |
