Witryna1 sty 2014 · As demonstrated in Section 3, the impurities are expected to influence a wide range of thermodynamic and other properties relevant to CO2 pipeline transport, including the density of the stream, the specific pressure drop and the critical point. WitrynaThe thickness of the melt film depends on the temperature, impurities, material properties and geometry. A temperature gradient is accompanied by a thermomolecular pressure gradient that drives the interfacial liquid from high to low temperatures and hence the particle from low to high temperatures, in a process called thermal regelation.
