Hunt, A J

The development of a new type of high temperature gas receiver that utilizes the direct absorption of concentrated solar flux by small particles suspended in the working fluid is described. The Small Particle Heat Exchange Receiver (SPHER) operates by injecting a very small mass of ultrafine carbon particles into a gas stream and exposing the suspension to concentrated sunlight that is passed through a window. The receiver can provide power to a Brayton cycle engine or supply industrial process heat. The advantages of this receiver are its simplicity, low pressure loss, light weight, and high efficiency. The analytical and experimental results to date are outlined including the optics of the small particle absorbers, the analysis of receiver efficiency and recent experimental results.
