“…Qualitative temperature distribution along the reactor function of the magnetomotive force applied to the coils at 3 A and 100 turns: A, t = 1 mn; B, t = 10 mn; C, t = 30 mn; D, t = 50 mn; E, inside the reactor reactor by convection and radiation heat transfer modes. 30,33 Initially, the fluid in the region between the conductive plate heats up and, by convection, transfers the heat to the reactor's inner cavity. Figure 6B has clearly described the instantaneous temperature distribution inside the reactor.…”

“…It is a reactor model integrated with an electromagnetic field designed by inspiring the existing solar-powered reactors in the literature 28,29,42,[47][48][49] that have proved the solar thermochemical energy conversion potential. Induction heating is based on electromagnetic fields distribution governed by Maxwell's equations described by Maxwell-Ampere, Maxwell-Faraday, Maxwell-Gauss equation, and magnetic flux law, respectively, expressed in Equations ( 1), ( 2), (3), and (4) [30][31][32]44,45 :…”

“…As indicated in Figure 6A,B, the rise in the reactor internal field temperature was observed around 10 minutes and quickly increased to 30 and 50 minutes as the heat flux was continuously diffused toward the reactor inner cavity from the heat source. Since higher species conversion efficiencies are obtained when the temperature distribution is more stable and when the overall temperature is high, 30,38,39 the uneven distribution of the instantaneous temperature distribution in terms of time in the heat storage medium should be more controlled for the reactor thermal performance.…”

In this study, the thermal and electrical performance analysis of an induction heating based-thermochemical reactor is investigated for high-temperature heat storage. The induction-heating model is built with Maxwell equations, and the surface-to-surface (S2S) radiation model is used for the induced and diffused thermal energy flow transport in the fluid phase within the reactor inner cavity. The effects of operating and structural parameters in terms of the coil turn number, coil current intensity and frequency, the conductive plate, and the coil's relative permeability, electrical conductivity, and emissivity could affect the heat generation, input power demand, and energy consumption of the proposed reactor performance are sufficiently investigated. It is found that the reactor temperature distribution resulted from the homogenized multi-turn coil magnetomotive force and frequency with the current intensity 48% more effective in reaching the desired temperature at the heat storage medium. However, the conductive plate relative permeability, electrical conductivity, and surface emissivity significantly affect the induction heating system's thermal power, with the relative permeability having the highest impact of 13% in the storage medium's temperature increasing at low current intensity. Moreover, the surface emissivity shows remarkable effects when the inducting heating operates at a high current. Significant energy consumption, more than 159%, is observed when the induction heating generator operates at steady-state mode. The reactor heating region temperature increases when the reactor operating current and frequency get high. It is observed that the more the induced heat was applied to the reactor, the more the reactor is heating up to a steady-state. The instantaneous temperature distribution inside the reactor depicted the rise in the temperature is caused by convection and radiation heat transfer. Higher and more uniform temperature distribution inside the reactor is obtained by optimizing the reactor operating and structural parameters.

“…It is worth noting that induction heating (IH) has been used for localized heat treatment in welded steel pipes to control tensile residual stresses [16][17][18]. Heat treatment with IH commonly is used for pipelines and pressure vessels, which are basically made of thick plates, and it is not generally applied to civil engineering structures, for example, steel bridges.…”

This paper presents experimental and numerical investigations on the characteristics of residual stresses generated by induction heating (IH) on 12 mm thick steel plates. IH at 250 • C and 350 • C provided high tensile residual stresses in the heating field but high compressive stresses away from the heating field. The double heating case generated higher compressive residual stresses-around 200 MPa-than the single heating case because of the superposition of the compressive residual stresses. It will be expected to improve the fatigue performance of welded joints when IH is applied for repair work on existing steel structural members susceptible to fatigue damage. Numerical simulation models for predicting residual stresses by IH were proposed by adopting the body heat flux input and the surface heat flux input. They will be beneficial for identifying the optimum heating conditions, such as the target temperature and the heating field, for applying IH to the actual repair work of the steel structural members.

“…Carburization is process of spreading carbon onto surface of steel components carried out at high temperatures, where after quenching, austenite produces a hardened martensitic surface [15]. Induction heating is a process of increasing hardness of steel surface obtained from rapid cooling of steel surface, previously subjected to heat from electromagnetic fields and induced currents [18].…”

The automotive industry's impact on development and improvement, reliability and lifetime, of components is significant. Automotive market encourages small and medium enterprises (SMEs) to enter this market, which is for SMEs a challenge to meet specified product quality. In this study, running-in wear analysis of transmission gears is conducted, which is rarely discussed in literature. Based on this study, one can make recommendations to SMEs to improve their product. Examination tests between an original equipment manufacturer (OEM) gear and SMEs gear product have been made. Results showed that mass and chemical composition are same. A clear difference between SMEs and OEM gear was seen from surface roughness and material hardness tests. SMEs gear exhibits a failure mechanism, and OEM gear does not indicate any failure indication during running-in period.
