Parametric optimization of supercritical power plants using gradient methods

Kler A.M., Zharkov P.V., Epishkin N.O. Parametric optimization of supercritical power plants using gradient methods // Energy. ID: 116230. 2019. DOI: 10.1016/j.energy.2019.116230 Gradient nonlinear optimization methods are among the most effective approaches to determine the optimal parameters of thermal power plants. These methods allow us to consistently optimize a large number of thermodynamic and design parameters and mass flow rates of actuation fluids and of heat-transfer fluids. This paper...

Performance modeling of thermoelectric devices by perturbation method

Marchenko O.V. Performance modeling of thermoelectric devices by perturbation method // International Journal of Thermal Sciences. Vol.129. 2018. P.334-342. DOI: 10.1016/j.ijthermalsci.2018.03.006 A nonlinear differential heat conduction equation for a leg of a thermoelement with temperature-dependent thermoelectric material properties is reduced to an integral equation. Its solution is obtained by a perturbation method in the form of a series in terms of powers of parameters proportional to Thomson...
