As shown in Figure 12, the volume expansivity of the propylene glycol solution has a larger effect than for water, but the impact is still relatively mild--only 9-13% of the pressure drop effect that is at most 10% of the total heat transfer rate per Figure 10.
Fortunately, the effect of volume expansivity is small in most cases, especially when the liquid is water.
The volume expansivity is easily computed from typically available density information via Equation (8), and so it is recommended that it be included in formulations for enthalpy differences such as Equation (14).
On the other hand, the effect of pressure drop on enthalpy is diminished for liquids with higher values of volumetric expansivity, such as hydrocarbon blends and silicone oils applied at elevated temperatures.
Thermal expansivity can be explained in terms of anharmonic vibrations of the polymer chains.
Figure 7 shows that the linear expansivity [[alpha].
The expansivity of the blends exhibits strong anisotropy at PLC concentrations as low as 5%.
Thermophysical evaluation of the expansivity of the material reveals the strong effect of PE in blends of PP and EPDM.
The highly oriented skin layer, though very thin, has a negative expansivity and high axial stiffness comparable to those of the highly drawn rod ([Lambda] [congruent] 15), thus constraining the expansion of the core region.
m] and [Mathematical Expression Omitted] are the thermal expansivity of the matrix and the fiber along the fiber axis.
The thermal expansivity of a composite is actually a thermomechanical parameter and depends on not only the thermal expansivities but also the elastic constants of the constituent phases.
