The paper outlines the concept of process intensification and integration, with a particular focus on sorption-enhanced, solid-catalyzed chemical processes. An alternative attractive solution to system parallel fixed-bed apparatuses is evaluated, which utilizes solids’ circulation in dual fluidized-bed reactor–regenerator system. This allows for continuous mode operation greatly simplifies cont...

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...

Abstract The manufacturing process and mechanical instability of high performance magnetocaloric materials hamper the implementation novel geometries for active magnetic regenerators. In this work, La(Fe,Si,Mn)13Hy is shaped into a regenerator with triangular microchannels hydraulic diameter 200–300 μm using that results in highly stable structure. characterized regards to heat transfer, resist...
