Analysis and optimization of exergy losses in a heavy water distillation column
Abstract: Heavy water (D2O) of isotopic purity 99.9% and more is used as the moderator and the coolant in pressurized heavy water nuclear reactors (PHWRs). This purity is maintained by vacuum distillation. In the column there are various sources of irreversibility and thermodynamic inefficiency. This work presents an analysis of these losses in a typical heavy water distillation column and their dependence on various design and operating parameters of the column. …

Thermal Modeling and Optimization of Irreversible Cogeneration Power Plant
Abstract: This paper aims at studying the cogeneration system coupled with outer heat reservoir of finite heat capacity and comprises of both external as well as internal irreversibility. External irreversibility is due to the finite-rate heat transfer between the working fluid and heat reservoirs while internal irreversibility is due to heat dissipation of working fluid. Both types of irreversibility are involved in the study on introducing an internal irreversible parameter which …

CFD-subset-FVM-based MATLAB-simulation of Heat Transfer in High Grade Cold Storage Augmenting Cryogenic Energy Storage System by Circulating Natural Gas as Working Fluid : Conceptual Review
Abstract: Abstract. Cryogenic Energy Storage (CES) improves power grid with renewable intermittent power sources. In CES, off-peak excess electricity liquefies air or natural gas. Cryogen is stored in large dewar tanks for long periods of time. Whenever electricity need is in peak, work is recovered from cryogen by a power cycle using waste heat. Many researchers focus on liquid air energy storage (LAES). But, natural gas is promising working fluid for …
