However, as will be shown below, the volume expansivity of certain fluids, such as hydrocarbon blends and silicone oils, is large enough to be of importance.
So different degrees of thermal expansivity are generated in different components of the machine tool, and the original relative positions between the components are altered.
p], [beta], and k denote time, velocity vector, temperature, pressure, stress tensor, shear rate, density, viscosity, specific heat, expansivity, and thermal conductivity, respectively.
From B and from handbook values of heat capacity C, volume thermal expansivity [beta], and volume V, we computed the effective Gruneisen parameter:
Building on expansive soils requires arrangements that generally depend on the expansivity of the soil, but these arrangements often generate some important over costs.
This means that thermal expansivity will drive the phase separation process.

That is because of the residual stress of heterogeneous polymers which produced by the differences of the physics properties (thermal expansivity, mechanics), internal structure and inter-solvating performance.
PVT experiments can provide key aspects of a polymer's physical properties by relaying the concepts of compressibility, expansivity and free volume (46).
