Abstract

This paper presents the temperature distribution of concrete storage systems, in which the oil inlet temperature for charging was 250 °C. This study was done based on the climatic conditions of Phitsanulok province, Thailan for concrete storage for a parabolic trough collector in the Energy Park of School of Renewable Energy Technology (SERT), the Naresuan University. The local materials volumetric ratios are water (1): cement (1): sand (1.5): rock (3) were suitable for use in a concrete storage system. The calculations of heat transfers could predict the temperature distribution and heat capacity within the concrete media and this system of analysis simulation helped to improve the efficiency of the storage system significantly.
