“…The cycle repeats until all the optimal combinations are found. Pairs that do not meet the requirements are returned for re-optimization to the portal load module [28][29][30][31]. The system provides an opportunity to exit from a stable state when the number of optimized pairs occupies the entire portal.…”

A generalized quality criterion is proposed for the processes of designing and manufacturing electrical equipment. The relationship between the parameters of the technological process of manufacturing electrical equipment and the ones of statistical plans acceptance quality control is taking into account for the calculation of the criterion. This creates the prerequisites for effective management of design and manufacturing processes to achieve the desired level of quality.

“…Heat flux per unit area was measured by the unique GHFSs with response time of 10 -8 … 10 -9 s. GHFSs have been developed, created and integrated into the laboratorial and industrial experience at "Thermophysics of Power Units" department of Peter the Great St. Petersburg Polytechnic University since 1996. Such a small response time of GHFS makes them practically inertialess instrument for study of most heat transfer types [4,5,6]. Figure 1 shows the scheme (a) and the general view (b) of the battery GHFS based on bismuth single crystals, which were used in our experiments.…”

For simultaneous investigation of heat transfer and hydraulic parameters of finned circular tube is proposed to connect PIV (Particle Image Velocimetry) method and thermal imaging with gradient heat flux measurement. In the first series of experiments, the hollow fin was investigated. The hollow fin was heated with saturated water steam and its isothermal surface simulated the ideal (isothermal) fin. The solid fin made of titanium alloy was investigated in similar regimes for comparison. In the second series, the influence of distance between fins on the heat transfer coefficients (HTC) at the circular fin, mounted on a circular cylinder was studied. The unique Gradient Heat Flux Sensors (GHFSs) were installed at different places of the fin surface. Comprehensive method including heat flux measurement, PIV and thermal imaging allows to study flow and heat transfer at the surface of the fin in real time. Possibility of complex study of flow and heat transfer for non-isothermal fins is shown.

A hybrid analytical‐computational method for three dimensional modeling of thermoelectric generators

2020

Summary A hybrid analytical‐computational method is developed to calculate the temperature distribution and electrical performance of thermoelectric generators (TEG). The geometrical complexities of thermo‐elements in real modules are ignored and the TEG is assumed to be made of five distinct layers. The power output is obtained by algebraic expressions and considered as a heat sink expression in the energy equation. The coupling of thermoelectric and energy equations is handled by developing user defined functions (UDF) in the numerical solution procedure. Accordingly, the heat flow is divided into two parts accounting for the thermoelectric phenomena and the Fourier conduction in the thermoelectric layer. The model is validated and the accuracy of the results is examined against two detailed simulations as well as the available experimental data. It is shown that the model is accurate with an average deviation of 8% to 10% compared to the experiments which is only 4% to 5% higher than the detailed rigorous numerical solutions. The influence of Thomson effect is also found to be around 1%. Moreover, the effect of element numbers with a certain amount of material is investigated and it is revealed that the appropriate number of elements depends on the module temperature due to the Thomson effect.
