    PERFORMANCE TESTING OF A PARABOLIC TROUGH COLLECTOR ARRAY FOR A SMALL-SCALE PROCESS HEAT APPLICATION
    (Turkish Soc Thermal Sciences Technology, 2018) Yilmaz, Ibrahim Halil; Hayta, Hakan; Yumrutas, Recep; Soylemez, Mehmet Sait
    This study presents the experimental investigation on performance testing of a parabolic trough solar collector (PTSC) array consisting of three modules connected in series. A new test setup has been proposed to test the thermal performance of this PTSC array in compliance with ASHRAE 93-1986 standard. The experimental tests have been carried out and monitored in a number of days under cloudless sky conditions in Gaziantep. In the performance analyses, the effects of beam radiation, collector inlet temperature, ambient conditions, and the variation in mass flow rate of the working fluid were investigated. The steady-state and dynamic tests of the PTSC array were performed. The efficiency tests were conducted with thermal oil for the temperature range from 50 degrees C to 200 degrees C, and mass flow rate of 0.1 kg/s to 0.5 kg/s under steady conditions. Additionally, the experimental results were compared with the results of the theoretical study made previously and gave good coherency.
