A stacked-screen regenerator is a key component in a thermoacoustic Stirling engine. Therefore, the choice of suitable mesh screens is important in the engine design. To verify the applicability of four empirical equations used in the field of thermoacoustic engines and Stirling engines, this report describes the measurements of heat flow rates transmitted through the stacked screen regenerator...

correlation of heat transfer coefficients for air flow through the regenerator constructed from randomly paked spheres is reported for the symmetric-balanced mode of operation. the experimental results have been correlated by the least square regression has been obtained.the present correlation has been compared with the heat transfer coefficient correlations in the literature.

In this paper, numerical solution of beta-type Stirling engine was presented considering its non-ideal regenerator. To this end, the second-order model including heat and power losses was used. Then, a numerical code was applied for calculating geometrical and physical optimum values of the engine. To confirm the obtained results, the physical and geometrical parameters of the GPU-3 engine were...

Different traditional and advanced control strategies have been tested and the performance investigated, revealing their incentives. The investigated control approaches are: conventional decentralized PID control, MPC control based on analytical model, MPC based on Artificial Neural Networks (ANN) model and Fuzzy Logic Control (FLC). Comparative control results are shown for the multivariable c...

This paper presents the exergy analysis and optimization of the Stirling engine, which has enormous potential for use in the renewable energy industry as it is quiet, efficient, and can operate with a variety of different heat sources and, therefore, has multi-fuel capabilities. This work aims to present a method that can be used by a Stirling engine designer to quickly and efficiently find nea...

Honeycomb ceramic is the key component of the regenerative system. The three-dimensional numerical model has been established for thermal process in honeycomb regenerator. The numerical simulation was performed using FLUENT, a commercial computational fluid dynamics (CFD) code, to compare simulation results to the test data. The regenerative process of a honeycomb ceramic regenerator was simula...

Here we give a brief description of the KTeV experiment [1] [2] . There were two configurations, E832 and E799, shown respectively in Fig. 1 and Fig. 2. . E832 was designed primarily to measure the direct CP violation parameter ǫ/ǫ, while E799 was devoted to rare KL decays. Two KL beams were generated by 800 GeV/c protons on a target. In E832 a regenerator in one of the beams converted KL to KS...

During the last years we have pioneered several new concepts for 2R optical regeneration. Two of these concepts, an active 2x2 multi mode interference (MMI) coupler and a Mach Zehnder interferometer with a regular semiconductor optical amplifier in one arm and an active 1x1 MMI in the other arm, have been fabricated as photonic integrated circuits. A third regenerator, a MachZehnder interferome...
