A comprehensive design methodology of organic Rankine cycles for the waste heat recovery of automotive heavy-duty diesel engines

A review of waste heat recovery and Organic Rankine Cycles (ORC) in on-off highway vehicle Heavy Duty Diesel Engine applications

“…Amicabile et al [74] proposed a comprehensive methodology for the design of ORC systems for automotive HDDE, considering heat sources and working fluid selection (also based on safety and environmental concerns), as well as some implemented costs correlations for the main components. Recuperated and non-recuperated cycles, as well as supercritical and sub-critical possibilities have been considered.…”

The Influence of Thermal Insulation Types on the Efficiency of the Heat Exchanger Operation in the System of Mobile Compressor Unit Thermal Losses Recovery

“…Актуальность поставленной цели обусловлена тем, что вся энергия, генерируемая в ДВС и затрачиваемая на сжатие газа в мобильной компрессорной установке, выбрасывается в окружающую среду в виде тепла. Рекуперация этой тепловой энергии обратно в установку в механической форме представляет собой актуальную научно-техническую задачу [5][6][7][8][9][10][11][12][13][14]. Известно, что рекуперация данных тепловых потерь может позволить вдвое увеличить производительность установки и уменьшить расход топлива на её привод.…”

Simple models for the heat exchange from exhaust gas to super- and sub-critical refrigerant R134a at high temperature differences

“…The heat exchanger is divided into 7 sections on the refrigerant side to correctly calculate the changes in the refrigerant heat transfer coefficient due to the changes in fluid properties transverse to the flow. 1 In order to determine the fluid properties at the wall, the respective average wall temperatures T Ex,W,a and T R,W,a are calculated as section-wise constant temperatures used to calculate the respective correction factors K T from Gregorig [28] and Krasnoshchekov and Protopopov [29], which are introduced with the governing equations in part 3.2.1.…”
