In order to provide the basic thermophysical property data for research of alternative clean fuels, liquid thermal conductivity methyl myristate, laurate and caprate which are considered as main compounds biodiesel was reported. The measurements three fatty acid esters, covering a temperature range from (292 372) K pressure up 15 MPa, have been performed by transient hot-wire technique with bar...

The resistance of metals is a function of applied pressure, and this dependence is large enough to be significant in the calibration of transient hot-wire thermal conductivity instruments. We recommend that for the highest possible accuracy, the instrument's hot wires should be calibrated in situ. If this is not possible, we recommend that a value of γ, the relative resistance change with press...

Supply voltage compensation is important to keep the accuracy for hot wire/hot film gas flow sensors. A compensation experiment device is established, the two steps curve fitting is presented to determine the functional relations among flow、sensor output and supply voltage, the coefficient of fitting polynomial is determined by Least Square method, thus eliminating the influence of supply volta...
