초록

This study focus on verification of the thermal efficiency of volumetric air receiver with $5kW_{th}$ Dish-type solar thermal system for high temperature uses by using numerical analysis compare with experimental data including shape change of absorber, direction of inlet and outlet. Porous material for radiation-thermal conversion used in former researches are substituted with the stainless steel wall installed along the spiral shaped flow path. Temperature variation and the flow change at the inside of the absorber has been analyzed by Star-ccm+ Version 3.02. Using the numerical model, the heat transfer characteristics of spiral type receiver for dish-type solar thermal systems are known and the thermal performance of the receiver can be estimated.
