We study numerically the possibility of using various gain-switched seed laser pulse parameters and fibers for a low-cost, all-fiber Mamyshev regenerator scheme. find that increasing durations, sufficient spectral broadening will be difficult to achieve in practice careful design system is required function. Furthermore, an optimal input peak power level can defined given fiber duration results...

This article presents the magnetic refrigeration technology that is based on magnetocaloric effect, heating or cooling of a material when applied field changes. The first part paper shows an introductory study evolution this over years, continuing with presentation regenerator model, which composed two heat exchangers parallel plates material, gadolinium and are separated by transfer agent flow...

This study investigated the energy conversion of a thermoacoustic engine using wet regenerator for interconversion heat flux density and work density. According to first law thermodynamics, local can be described source corresponding gradient First, we analytically separated phenomena related water evaporation condensation. Thereafter, experimentally only gas, then that The data obtained were c...

This research article illustrates a numerical study of single stage coaxial as well as inline Inertance-Type Pulse Tube Refrigerator (ITPTR). In this present work a computational fluid dynamic (CFD) approach has been adopted for numerical simulation purpose. The detail analysis of cool down behaviour, heat transfer at the cold end and the pressure variation inside the whole system has been carr...
