Asymmetrically heated multi-stage travelling-wave thermoacoustic electricity generator

Algorithmic optimisation of the electrical power output of a low-cost, multicore thermoacoustic engine with varying resonator pressure

“…streaming and thermal radiation [26]. Kisha, et al [27] reported a decrease in power from the numerical model to experiment of 27-32% and Riley [11] reported decreases of 30%.…”

“…The TAE under investigation by this paper is the asymmetrically heated, twin-core SCORE stove prototype, pictured in Figure 2a). A model of this TAE has been developed and validated in DeltaEC by Kisha, et al [27], of which the layout is shown in Figure 2b). The majority of the dimensions of the system are defined by either previous design processes or premanufactured parts and can be found in a thesis by Chen, et al [5].…”

“…The engine receives 2.5 kW of heat input, with 40% of the heat applied to core 1 and 60% of the heat applied to core 2. The current model outputs 31.4 W of electrical power [27]. The boundary conditions for the DeltaEC model are:…”

Enhancing Thermo-Acoustic Waste Heat Recovery through Machine Learning: A Comparative Analysis of Artificial Neural Network–Particle Swarm Optimization, Adaptive Neuro Fuzzy Inference System, and Artificial Neural Network Models

“…In their study, Kisha et al [8] proposed a thermo-acoustic engine designed to efficiently convert thermal energy into acoustic power, ultimately translating it into electricity. The working medium for this innovative system was air at atmospheric pressure.…”

“…The investigation focused on understanding the impact of various heat sources on the conversion of heat to acoustic energy. Key parameters such as pressure amplitude, volume flow rate, acoustic impedance, and onset temperature difference were systematically studied [8]. The findings revealed that these parameters were significantly influenced by the method of inputting thermal energy from heat-distribution sources.…”
