What is Investigation on Heat and Mass Transfer Characteristics and Parameter Design of the Maisotsenko Saturator about?

Abstract The Maisotsenko gas turbine cycle (MGTC) introduces the M-cycle in the aftercooling process, thereby adding a larger mass flow rate to the saturator. However, this imposes strict requirements on the lightweight design of the aftercooling saturator, for which detailed manufacturing information is currently scarce. This paper presents a comprehensive MGTC that combines intercooling, aftercooling, and regenerative, and considers the reuse of cooling water and energy recovery. The thermodynamic indicators are obtained by establishing energy and mass conservation models for each component. A heat and mass transfer model is developed for the aftercooling saturator, and the actual dimensions and internal temperature, relative humidity, and humidity ratio changes are calculated using the finite difference method. The response patterns of channel length to changes in parameters such as pressure ratio, dew point efficiency, and extraction ratio are analyzed. The results show that with a pressure ratio of 16, a dew point efficiency of 0.8, and an extraction ratio of 1/3, a channel length of 5.526m is required, with a corresponding channel number and total heat transfer area of 317 an
