This document is intended to familiarize potential users with the capabilities of DRAC (Dynamic Receiver Analysis Code). DRAC is the first in a series of user friendly driver programs for the more general code, TOPAZ (Transient-One-Dimensional Pipe Flow Analyzer). DRAC is a relatively easy-to-use code which permits the user to model both transient and steady-state thermohydraulic phenomena in solar receiver tubing. Users may specify arbitrary, time-dependent, incident heat flux profiles and/or flow rate changes and DRAC will calculate the resulting transient excursions in tube wall temperature and fluid properties. Radiative and convective losses are accounted for and the user may model any receiver fluid (compressible or incompressible) for which thermodynamic data exists. A description of the DRAC code, a comprehensive set of steady-state validation calculations, and detailed user instructions are presented.
