Summary Details

Concentrating Solar Power Receiver (CSPs) collect solar radiation with large mirrors and reflect them concentrated on a receiver. Here, a Dish-Stirling type thermal cycle is driven. One of the key preconditions for a cost competitive production of power is a good efficiency factor.

Within the framework of this project, we want to examine and qualitatively quantify the heat losses of a Dish Sterling Concentrating Solar Power Receiver. It is the aim to determine the individual driving forces for heat losses by analysing natural convection on the one hand and two different setups of forced convection on the other hand.

In section 2, we present the abstract model of a solar receiver. Then, we will discuss the necessary models to simulate turbulent flow and heat transfer of air and justify our choice of numerical methods to solve the governing equations in ANSYS Fluent. Furthermore, we will introduce performance factors to monitor the heat losses of the solar receiver.

Coherent with the two main physical phenomena of heat losses, we subdivided the report in normal convection (NC, section 3) and forced convection (FC, section 4), where we outline the specific model characteristics, boundary conditions, grid requirements and benchmarks respectively. A profound analysis of the results and an outlook on further research in section 5 finalise the report.
