currents
The effect of eddy thermoelectric currents in homogeneous thermoelectrically
anisotropic and isotropic inhomogeneous media has been studied under various
thermal boundary conditions. The effect of transverse temperature difference
origination has been explained.
Lutsyak V.S. Theoretical analysis of thermoelectric figure of merit
of nernst-ettingshausen generator and cooler
It has been shown that the efficiency and maximum temperature difference
of Nernst-Ettingshausen generator and cooler is considerably affected by
the difference in coefficients of thermal conductivity in the absence of
electric current and field

and thermoelectric parameters of cold-pressed pbte samples during annealing
The results of investigating variations in dimensions and electric
conductivity during the isothermal annealing of cold-pressed samples of
PbTe based medium-temperature materials have been given. The increase in
samples dimensions in the direction of pressing and the oscillating behaviour
of electric conductivity in the initial annealing stage have been established.
The time of reaching equilibrium has been determined.
Anatychuk L.I., Mikhalchenko V.P. On the anisotropy of thermoelastic
properties of CdSb single crystals
The anisotropy of thermal elasticity of cadmium antimonide crystal
lattice (rhombic crystal system, space group D2h15) correlated to the anisotropy
of thermoelectric properties has been analyzed. A correlation in high symmetry
directions has been established, and the directions of extreme values of
piezothermopower and thermoelectric figure of merit have been indicated.
Cross-sections of Young’s modulus characteristic surfaces have been constructed
that can be used in the design and manufacture of CdSb based thermoelectric
devices.

Medved A.I. Thermoelectric and elastic properties of fe-ni-ti-al
alloys in the martensite-austenite states
Thermoelectric coefficient and Young's modulus of N26UT3 and N26UT2B
Fe-Ni-Ti-Al alloys have been experimentally studied in various martensite-austenite
states. The specific features of the influence of joint titanium and aluminum
doping and niobium microdoping on the process of phase-structural transformations
in Fe-26Ni matrix have been analyzed. It has been discovered that the alloys
under study acquire maximum elasticity and minimum thermoelectric coefficient
value in the martensite-austenite state at the reverse austenite content
about 20%.

The paper deals with heat loss reduction in thermoelectric generators
with catalytic heat source based on separate fuel and air delivery. Partial
heat recovery of fuel combustion products has been shown to increase thermal
generator efficiency by 10-12%.

Skrishevsky V.A., Tretyak O.V., Ustilko V.Yu. The influence of temperature
on the heat exchange in thermoelectric sensor of water consumption based
on Bi2Te3.
The opportunities of using Peltier thermoelectric element as a semiconductor
sensor of water flow rate and consumption have been analyzed. The influence
of water flow on heat exchange conditions and electrical characteristics
of sensors with semiconductor thermoelectric elements based on Bi2Te3 has
been analyzed. The use of comparison circuit with two in-series thermoelements
allows compensation of temperature changes in semiconductor sensor parameters
over a wide temperature range. Conditions for the optimization of measuring
modes have been determined as a function of the influence of external factors
(temperature, mobile medium properties)
