Numerical Simulation of Heat Transfer in a 3D Cavity-Receiver
Volume 2: Photovoltaics; Renewable-Non-Renewable Hybrid Power System; Smart Grid, Micro-Grid Concepts; Energy Storage; Solar Chemistry; Solar Heating and Cooling; Sustainable Cities and Communities, Transportation; Symposium on Integrated/Sustainable Building Equipment and Systems; Thermofluid Analysis of Energy Systems Including Exergy and Thermoeconomics; Wind Energy Systems and Technologies, 2015The unsteady 3D fluid flow coupled to radiative, convective, and conductive heat transfers are computed within a cavity-receiver that was successfully tested experimentally. A Monte-Carlo radiation model is used in the fluid regions of the reactor with source terms outside the cavity’s window to account for the concentrated radiative power input. Darcy’

Selection of Surface Reflectivity for a Solar Cavity Receiver
Volume 1C, Symposia: Fundamental Issues and Perspectives in Fluid Mechanics; Industrial and Environmental Applications of Fluid Mechanics; Issues and Perspectives in Automotive Flows; Gas-Solid Flows: Dedicated to the Memory of Professor Clayton T. Crowe; Numerical Methods for Multiphase Flow; Transport Phenomena in Energy Conversion From Clean and Sustainable Resources; Transport Phenomena in Materials Processing and Manufacturing Processes, 2014The thermal performance of a saturated steam solar cavity receiver was numerically studied. In order to improve the uniformity of heat flux and wall temperatures on the boiling tubes, the proper selection method of the surface reflectivity for the boiling tubes and the other cavity walls was found.

A model of a solar cavity receiver with coiled tubes
The Proceedings of Mechanical Engineering Congress, Japan, 2017Abstract A model of a solar cavity receiver using helically coiled tubes as heat absorber is developed. The receiver geometry of the model mimics that of an experiment for a Cross Linear concentrating system, although the model has a potential for application to the same type of receivers.

Prediction Techniques for Cavity-Crystal Receivers
IEEE Transactions on Electromagnetic Compatibility, 1969A technique is presented for the reliable prediction of spurious response and intermodulation interference characteristics for microwave receivers of the cavity-crystal type. Calculation procedures, data collection, and simplification measures are given. The results of a test prediction using a typical microwave communication receiver are presented.

Thermal Modeling of Solar Central Receiver Cavities
Journal of Solar Energy Engineering, 1989Results are presented from a numerical model of the steady-state energy transfer in molten-salt-in-tube solar cavity receivers that includes convective energy transfer at a local (spatially resolved) level. Molten salt energy absorption and gray radiative transfer between all cavity surfaces are also included.

Results on the Performance of the Sulzer Cavity Receiver and the Franco-Tosi External Receiver
1986This paper presents some of the results of evaluation performed on the cavity receiver (Sulzer) and the external receiver (ASR) installed at the IEA/SSPS project. These two different receiver concepts were tested in the 500 kW central receiver system experiment at the Small Solar Power Systems Project in Almeria, Spain. Both receivers use liquid sodium

Design of a Cavity Heat Pipe Receiver Experiment
SAE Technical Paper Series, 1992<div class="htmlview paragraph">A cavity heat pipe experiment has been designed to test the critical issues involved with incorporating thermal energy storage canisters into a heat pipe. The experiment is a replication of the operation of a heat receiver for a Brayton solar dynamic power cycle.

An Air-Based Cavity-Receiver for Solar Trough Concentrators
ASME 2010 4th International Conference on Energy Sustainability, Volume 2, 2010A cylindrical cavity-receiver containing a tubular absorber that uses air as the heat transfer fluid is proposed for a novel solar trough concentrator design. A numerical heat transfer model is developed to determine the receiver’s absorption efficiency and pumping power requirement.

Convection Heat Loss From a Cavity Receiver
Journal of Solar Energy Engineering, 1984The receiver whose convective heat loss test results are presented was designed to absorb 5 MW of solar energy, using a molten salt working fluid. During the tests, this receiver was brought to a temperature of about 343 C by a small group of heliostats.
