state-point simulations determining: (1) the potential energy U0, (2) the virial W0, (3) the temperature T0, (4) the excess isochoric specific heat , (5) the density-scaling exponent γ0 and (6) the derivative of CVex along the isomorph via the quantity B0 defined in equation (12)...
Classically, the critical point of the free-energy curve is a maximum and defines the nucleation barrier, or the energetic barrier after which continued ice growth will lower the free energy of the system indefinitely until the entirety has changed phase. In the isochoric case however, ice growth...
Equation 1 The freezing point of a pure liquid is determined experimentally by making measurements of the temperature as a function of time while the sample is submerged in a constant temperature bath at a temperature below that of the freezing point of the substance. The data (Temperature vs...
Theory shows that the excess ßQ of volume or heat content change, which arises from actual formation of small amounts of liquid at a temperature T below the limiting melting point Tr0, in such cases is related to the total change ßQ0 by the equation where K is the cryoscopic ...

When a water droplet rests on a cold surface whose temperature is below the freezing point, it solidifies into an ice pellet. In industry, icing is usually not desired because it can cause damage to several processes such as crop production, power generation, building infrastructure, ...
From a practical point of view, it is convenient to rewrite Eq. (5) using adjustable parameters of a system such as the magnification of the imaging system (M) and the number of lines in the direction perpendicular to the flow direction (Ny). Some of the above parameters are expressed by...
