Dynamic Simulation and Experimental Research of Open Air Receiver System with Ceramic Foam Absorber
Abstract
This study investigated the heat transfer between air flow and ceramic foam absorber in open air receiver system using dynamics simulation based on Modelica language and Dymola solver. The experimental platforms of air receiver were built to validate the model, and the comparison between the experimental data and the simulation results showed this model was reliable to predict the dynamic performance of the air receiver system and to help optimize this system. The methodology of the model development and the implementation of the experiment are presented in this paper. Relied on the validated air receiver model, the sensitivity studies had been done to explore the influence of the absorber geometric parameters (thickness, mean cell size and porosity) on the volumetric ceramic foam air receiver performances. In addition, the optimization of the foam air receiver with the thermal efficiency as the objective function had been carried out based on the air receiver model and the optimization tool in Dymola.
