Correct numerical simulation of a two-phase coolant
Thermal Engineering - Tập 63 - Trang 98-106 - 2016
Different models used in calculating flows of a two-phase coolant are analyzed. A system of differential equations describing the flow is presented; the hyperbolicity and stability of stationary solutions of the system is studied. The correctness of the Cauchy problem is considered. The models’ ability to describe the following flows is analyzed: stable bubble and gas-droplet flows; stable flow wi...... hiện toàn bộ
Factors and Mechanisms Causing Wear of Turbine Heating Steam Condensate Pipeline Components at a Nuclear Power Plant
Thermal Engineering - Tập 66 - Trang 662-671 - 2019
The article considers the specific features related to operation of the power valve and orifice lines within turbine plant piping systems whose inlets receive water medium with saturation parameters (separated moisture or condensate). It is shown that transportation of working medium in these piping systems is accompanied by pressure drop, boiling, and formation of various two-phase flow patterns ...... hiện toàn bộ

A Hybrid Solar–Geothermal Heat- and Hot-Water Supply System
Thermal Engineering - Tập 68 - Trang 564-569 - 2021
The cooling of rock formations when extracting heat by a borehole heat exchanger and the restoration of the thermal field in the rock during the idle time of the well have been investigated. The heat in the rock during the summer downtime of the well is partially restored due to the influx of heat from the outside formation. The radius of the rock cooling front around the borehole in the heating p...... hiện toàn bộ
Simulation of porous transpiration cooling of the leading semicylindrical edge of a streamlined body
Thermal Engineering - Tập 58 - Trang 748-751 - 2011
Experiments are carried out for simulating the efficiency of cooling the leading edge of a blunt streamlined body made of porous reticular material with an impermeable insert placed along the stagnation zone. Satisfactory results are obtained that make it possible to recommend the proposed method of organizing transpiration porous cooling of the leading edge of the blades used in high-temperature ...... hiện toàn bộ

The Fastest Response Algorithm for Thermal Plants with a Time Delay: Application in a Hybrid System Containing a PID Controller and an Automatic Tuning Unit
Thermal Engineering - Tập 66 - Trang 550-559 - 2019
The article discusses matters concerned with improving the performance of automatic closed-loop control systems of thermal plants with a time delay in responding to a change in the setpoint. The improvement is achieved by applying the fastest response algorithm (FRA) according to the Pontryagin maximum principle and using linear prediction of the controlled variable. It is shown that, during opera...... hiện toàn bộ
