Thermal diffusivityis therate of transfer of heat of a material from the hot side to the cold side- a measure of how quickly a material can absorb heat from its surroundings. It can be calculated by taking the
At constant pressure, water thermal conductivity increases with temperature up to a maximum value around 200°C. Under supercritical conditions, thermal conductivity decreases due to the rupture of the hydrogen bonds. For this reason, heat transfer coefficients are higher around the critical point and...
An iterative method of calculation was used to determine the thermodynamic properties in the same P-T diagram. Anomalies observed for the isothermal compressibility and the specific heat at constant pressure are discussed in terms of statistical mechanical considerations....
