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 Carbon-dioxide-based trans-critical power cycle is a novel technology for waste heat recovery. This can handle the high-temperature exhaust gas and be built in compact size, which an important feature auxiliary equipment internal combustion engine. To obtain best output, four configurations were constructed: basic system; one with preheater, another regenerator fourth preheater regener...

This thesis investigates the use of Semiconductor Optical Amplifiers (SOA) for 10 and 40Gb/s all-optical 3R signal regeneration and wavelength conversion for application to advanced high-speed all-optical WDM networks. Detailed experimental characterisation of the magnitude and the time scales of inter­ band nonlinear effects in SOA is carried out. The regenerative properties of SOA gates are t...
