particle‐SCO2 moving packed bed heat exchangerThis article proposes a dynamic analysis framework for a shell and plate particle-SCO2 MPBE with straight SCO2 channel and four fins-modified SCO2 channels, which contains a static model and a dynamic model. 13 cases covering an initial temperature...
The utility model belongs to the field of mechanical engineering, and particularly relates to a connecting structure of a tube plate, a shell and a channel of a shell-and-tube heat exchanger. The connecting structure comprises the tube plate, a channel flange and a shell flange, a channel si...
The utility model provides a pass partition plate for a channel of a shell-and-tube type heat exchanger. The pass partition plate is composed of a first partition plate, a second partition plate and a third partition plate which are sequentially bent and connected, wherein the first partition...
The particle-to-sCO2 heat exchanger plays a significant role in coupling the high temperature particle receiver to supercritical carbon dioxide Brayton cycle in concentrating solar power plants. In this work, heat transfer characteristics of a shell-and-plate, moving packed-bed heat exchanger are ...
Four different fin configurations on SCO2 channel side are presented, analyzed and compared via the static model at the design-point case. Offset rectangular fins configuration behaves the best heat transfer enhancement in total heat transfer rate and overall heat transfer coefficient when compared ...
This allows for the design tradeoffs in heat exchanger geometry and particle properties to be explored on the heat exchanger conductance and sCO(2) pressure drop. Overall heat transfer coefficients for the particle-to-sCO(2) heat exchanger at CSP operating temperature (500-800 degrees C) can ...
The authors proposed a design of a small heat exchanger with a shell-and-tube structure, where the refrigerant condenses on the outer surface of the pipe minichannels cooled from the inside with water. It is a response to the global trend of building highly efficient, miniaturized structures ...
