The volume expansivity is readily calculated from the density function according to Equation (8).
Volume expansivity as functions of temperature and concentration are shown for various other common heat transfer fluids as follows (3): Figure 4a) propylene glycol aqueous solutions as DOWFROST[R] (DOW, 2008), Figure 4b) potassium formate aqueous solutions as Dynalene HC (Dynalene, 2001), Figure 4c) a hydrocarbon blend as Dynalene HF-LO (Dynalene, n/d), and Figure 4d) silicone heat transfer fluid as Syltherm[TM] HF (DOW, 2001).
In either case, there is a large expansivity mismatch between that of the chip (6 ppm/K) and TPI (20 ppm/K).
Numerous attempts have been made to solve the expansivity mismatch problem, typically using various nonconductive adhesives [2].
BL/CF] for the effective Young's modulus, effective linear expansivity and volume fraction, respectively, of a hypothetical BL/CF shell/core composite structure.
Treatment of the experimental data (Table 1) by Eqs 3 (assuming a/b [approximately equal to] 30 and lower bounds for effective Young's modulus and linear expansivity of the BL) yielded [[Delta].
We note that the thermal expansivity [Alpha] in Eq 4 is assumed to be caused by the anharmonicity of molecular vibrations.
Nevertheless, a peculiar behavior is observed for the transverse expansivity above the [T.
To this end, both systems have been investigated to interpret changes in expansivity with temperature and stress level.
Irreversible changes in material properties may be caused by the hydrolyzing potential of water, swelling and deswelling, and the differences in expansivity of the incorporated water and matrix.
The mechanical properties of in-situ composites have been extensively studied (1-8), but other physical properties such as thermal conductivity and thermal expansivity have received much less attention.
