Abstract

The effect of the multi-row nozzle arrangement to the thermal performance of an impinging solar receiver is studied, and new governing equations are introduced for modifying the earlier introduced inverse design method. With the help of the modified inverse design method and a numerical conjugate heat transfer model, an impinging receiver based on stainless steel 253 MA material has been designed for the combination of a micro gas turbine and the EuroDish collector system. At a DNI level of 800 W/m², the average air temperature at the outlet and the thermal efficiency can reach 1071.5 K and 82.7%. Furthermore, the temperature differences on the absorber can be reduced to 130 K and 149 K for two different DNI levels respectively. This represents a greatly improvement compared with other published cavity receiver designs.
