“…For mesh size 30 strands/inch, the oscillations began at nearly 206 °C. The pressure drop and prolonged acoustic oscillation occurred due to fine meshing which creates obstacle to acoustic wave (Fujita et al, 1983). As a result, oscillations started for fine mesh with 80 strands/ inch at a temperature of approximately 282 °C.…”

This paper focuses on the numerical and experimental investigation of the small-scale power generator. The travelling wave thermoacoustic power generator is numerically analyzed and experimentally tested. The cyclic analysis is used to carry out numerical analysis of the power generator. The system is operated on atmospheric pressure, which allows the manufacturing of an acoustic feedback loop using Polyvinyl chloride piping. The acoustic power generated inside the generator is harnessed by the low-cost linear alternator, i.e., loudspeaker. The effect of regenerator wire mesh on performance of the power generator is numerically analyzed and validated experimentally. The numerical analysis identifies the temperature variation, pressure fluctuation, volume flow rate inside the system, and acoustic power distribution. The maximum electric power experimentally generated by the small-scale power generator is around 45 W with overall efficiency 8.30%. The alternator generates the maximum electric power at the optimum location, i.e. 2.30 m away from the engine core.

“…The engine has an alpha-type con guration, cylinder bore of 220 mm and a crank drive mechanism, with variable phase angle and stroke that can be set either to 150 or 300 mm for research purposes. The details and performance information of the prototype have been published by F ujita and co-authors [23] of M itsubishi H eavy Industries Limited and D aihatsu D iesel M anufacturing Company Limited, Japan. The engine was brake tested at a mean pressure from 6 to 12 M Pa with helium as the working uid.…”

Dimensional analysis is applied to both leakage and mechanical power losses in order to obtain the set of parameters that influence power performance of the kinematic Stirling engine. An empircical model of mechanical power losses is proposed to complete the indicated power model previously introduced by Prieto and co-workers. That approach is mainly based on the characteristic Stirling number and allows the performance of known prototypes to be analysed from the viewpoint of indicated power, brake power and mechanical efficiency. After showing that similarity criteria can be extended to brake power performance, scaling factors have been derived for typical scaling cases. Some examples show that quasi-static simulation and scaling techniques may be combined to support preliminary design procedures.

This paper reports on the problems encountered and their subsequent solution during the development and construction of an advanced locomotive from prototype to full production assembly. A fleet of these locomotives are to work in the UK National Coal Board's (NCB) Selby coalfield. In order to ensure that all the information was accurately recorded and could be applied to a reasonably precise point in the development process, visits were made to the company at intervals of about two weeks. In developing products of this nature a strongproblem solving capacity is a necessity and in the main it was found that engineering and theoretical design problems were solved quickly and once solved did not recur on subsequent units. Strong links between specialist suppliers and customers are vital, since components will often be used in unfamiliar applications and the customer may have to spend time carrying out applied development of suppliers' components. The development and production of the locomotive would have been aided by the NCB providing more accurate specifications, giving an indication of future volume requirements and being better prepared to site test the prototype after its delivery.
