“…The model has also been compared to Eulerian two phase computational fluid dynamics (CFD) simulations of granular flow between pipes, in Ansys Fluent®, by Baumann and Zünft. This work was related to heat exchangers for concentrating solar power plants (Baumann & Zunft 2012;Baumann et al 2013;Baumann et al 2014). Baumann and Zünft also compared the Niegsch et al model and their CFD simulations to experimental results, collected by means of particle image velocimetry, with good agreement.…”

The Helium Extraction & Acquisition Testbed (HEAT) is an experimental lunar volatiles extraction system designed to test recuperative heat pipe heat exchanger (HPHX) technology that could be used to release volatiles from lunar regolith. HEAT has passive and active granular flow components that allow for the controlled flow of regolith through a variety of HPHX configurations. HEAT has instrumentation to measure regolith and heat pipe temperature at key positions in the device to ascertain the HPHX recuperative efficiency of the device. Volatile gas release is also measured with the use of a residual gas analyzer. The primary volatile of interest for this investigation is helium-3 (3 He). As a surrogate for 3 He containing regolith, 4 He containing JSC-1A regolith simulant is used. A summary of the design of the HEAT device and an overview of the modeling approach for an HPHX is discussed in this paper.

Abstract. Within the framework of the project HiTExStor II, a system model for the entire power plant consisting of volumetric air receiver, air-sand heat exchanger, sand storage system, steam generator and water-steam cycle was implemented in software "Ebsilon Professional". As a steam generator, the two technologies fluidized bed cooler and moving bed heat exchangers were considered. Physical models for the non-conventional power plant components as airsand heat exchanger, fluidized bed coolers and moving bed heat exchanger had to be created and implemented in the simulation environment. Using the simulation model for the power plant, the individual components and subassemblies have been designed and the operating parameters were optimized in extensive parametric studies in terms of the essential degrees of freedom. The annual net electricity output for different systems was determined in annual performance calculations at a selected location (Huelva, Spain) using the optimized values for the studied parameters. The solution with moderate regenerative feed water heating has been found the most advantageous. Furthermore, the system with moving bed heat exchanger prevails over the system with fluidized bed cooler due to a 6 % higher net electricity yield.
