Thermoelastic effect in liquid mercury at high hydrostatic pressures

چکیده
The rapid deformation of liquid and solid materials usually results in temperature changes. This rapid deformation is considered to be a nearly adiabatic process where the heat generated during the deformation changes the temperature of the material. Early experiments showed that metals cooled down on sudden stretching and warmed up upon compression [1]. In 1805, Gough [2] observed that the temperature of a rubber band increased when it was suddenly stretched and decreased when the force applied was released. These reversible thermomechanical effects, also defined as the thermoelastic effect, were later widely studied by Thomson (Lord Kelvin) [3]. In 1853, Thomson [4] proposed a general thermodynamic formula that described the change in temperature as the result of the rapid application of pressure on fluids. This Thomson equation can be written as

Wave Propagation in Fibre-Reinforced Transversely Isotropic Thermoelastic Media with Initial Stress at the Boundary Surface
The reflection and transmission of thermoelastic plane waves at an imperfect boundary of two dissimilar fibre-reinforced transversely isotropic thermoelastic solid half-spaces under hydrostatic initial stress has been investigated. The appropriate boundary conditions are applied at the interface to obtain the reflection and transmission coefficients of various reflected and transmitted waves wi...

We have developed a technique for cultivation of chemolithoautotrophs under high hydrostatic pressures that is successfully applicable to various types of deep-sea chemolithoautotrophs, including methanogens. It is based on a glass-syringe-sealing liquid medium and gas mixture used in conjunction with a butyl rubber piston and a metallic needle stuck into butyl rubber. By using this technique, ...
متن کاملInfrared absorption of solid nitrogen at high pressures.
We have observed infrared absorption peaks in solid nitrogen at hydrostatic pressures as high as 7 GPa at liquid-helium temperatures. The shift in the AlSb:CSb local vibrational mode is used to precisely calibrate the pressure. For all measured pressures we also observe the n3 vibrational mode of CO2 impurities. For pressures greater than 1.9 GPa, a peak appears which we attribute to a N-N stre...
متن کاملEffect of hydrostatic pressure on succinic, formic, and malic dehydrogenases in Escherichia coli.
ZoBell and Morita (1957) demonstrated the existence of barophilic bacteria in various deeps and trenches of the Pacific and Indian Oceans where hydrostatic pressures up to 1,100 atm exist. However, the relationship between hydrostatic pressure and the activity of life in the deep sea is still unknown. Johnson et al. (1954), for convenience of discussion, divided hydrostatic pressure into modera...

The three-phase-lag model and Green–Naghdi theory without energy dissipation are employed to study the deformation of a two-temperature fiber-reinforced medium with an internal heat source that is moving with a constant speed under a hydrostatic initial stress and the gravity field. The modulus of the elasticity is given as a linear function of the reference temperature. The exact expressions ...
