thermomeˈchanical, a.
[f. thermo- + mechanical a. and n.]
a. Physics. Designating or referring to an effect observed in helium II in which the liquid tends to flow from a region of lower to one of higher temperature.
1939H. London in Proc. R. Soc. A. CLXXI. 484 By maintaining a temperature gradient along the capillary, it is thus possible to produce a flow of helium against a pressure gradient... The phenomenon which we shall call the ‘thermomechanical effect’ reveals a new mechanism by which heat can be transformed into mechanical work. 1959K. R. Atkins Liquid Helium i. 11 The thermo⁓mechanical pressure difference Δp arising from a temperature difference ΔT is given by Δp/ΔT = Q*/TV, where Q* is the heat transfer associated with the transfer of unit mass..and V is the volume of unit mass. 1964[see mechanocaloric adj. s.v. mechano-]. 1974D. R. & J. Tilley Superfluidity & Superconductivity i. 9 These manifestations of the thermomechanical effect show clearly that heat transfer and mass transfer in the II are inseparable.
b. gen. Both thermal and mechanical; spec. in Metallurgy, involving simultaneous thermal and mechanical treatment to achieve results not obtained when they are applied separately.
1974Sci. Amer. June 34/3 The less energetic ions (thermal deuterons and tritons)..are capable of producing sharp thermomechanical stresses in a thin skin of the first wall. 1975Nature 7 Aug. 455/3 The uncertainty in geochemical characteristics, especially of the radiogenic isotopes, leaves many degrees of freedom in predicting the present thermo-mechanical state of the interior [of Mercury]. 1976Ibid. 22 July p. iii. (Advt.), The journal will welcome papers concerned with the relevant areas of materials technology and metallurgy, e.g. thermomechanical treatments. |
