Abstract-This paper describes a universal thermal dynamic non-linear model for water tube drum boilers. The model that suit for model-based control is derived from first principles. It can be characterized by a few physical parameters that are easily obtained from construction data and steam tables. And the model is developed which enables the prediction of riser temperature of water tube boilers...
Vacuum solar receiver is the key component in parabolic trough solar system. Due to different expansion increment between metal absorber and glass, corrugated expansion joint (metal bellows) is necessary to compensate the extra expansion increment. The mechanical and thermal properties of metal bellows have significant influence on the reliability and heat loss of solar receiver. Recently, China's...
The thermal control of developing nano-satellite will be challenging due to the continually rising tendency of the power densities on board and the complicatedly ever-changing orbital thermal environment. The paper is aimed at modeling and analysis of an active thermal control system for on-orbit nano-satellite used MEMS (Micro Electro Mechanical Systems)-based pumped liquid micro channel efficient...
