“…The thermophysical properties of metals and alloys are the most important physical characteristics that determine the patterns of their behaviour under various operating conditions [1][2][3][4][5][6][7][8][9][10][11]. The main interest in doped alloys is primarily due to the possibility of significant improvement, and sometimes a fundamental change in the physicochemical properties of known materials.…”

The kinetics of cooling of the aluminium grade of the A5N, its alloys doped with silicon, copper, and rare-earth metals in a wide temperature range were measured. It revealed that the process of cooling of the aluminium and its alloys has a relaxation behaviour. An experimental study of the specific heat and heat transfer coefficient of these substances is carried out. According to experimental data, the temperature dependence of the heat transfer coefficient for pure metals is calculated. It is shown that the values of heat transfer coefficients of copper, aluminium, and zinc are different. To determine the heat capacity of doped alloys for each group is recommended to define the coefficient of heat transfer of the initial alloy.

The principal context of this study was a combined heat and power plant (CHPP) system, with the aim of conducting the multi-objective optimization (MOO) of an energy, exergy, and economic (3E) analysis. To meet rising energy demands, optimal operational conditions for CHPPs are required. Enhancements to plant equipment and improvements in plant design are critical. CHPP design has its basis in the first law of thermodynamics; the losses from such systems are therefore most accurately determined via exergy analysis. Energy quality can also be assessed using exergy analysis. Consequently, it is possible for the designers of thermodynamic systems to apply the findings to achieve improved efficiencies. The economic aspect of CHPP optimization is also critical because the structure is highly complex. This study therefore makes use of a Henry gas solubility optimization (HGSO) algorithm in a CHPP base case situation to achieve MOO. In this particular CHPP system, the respective enthalpy and exergy efficiencies were increased in the case of the boiler (7.22% and 7.21%), the turbogenerator (4.52% and 6.84%), and the condenser (3.06% and 31.37%). In this study, four scenarios are proposed, whereby the design of a heat exchanger network (HEN) aims to optimize energy savings and economic performance through analysis of the profits generated through electricity and steam production. A payback period of around two to three years was reported, where the cost increase under optimal conditions was found to be 0.3824%. The results demonstrate clearly that the tested techniques may be appropriate in practical scenarios when enhancing CHPP performance in the context of the base case.
