## Computational fluid dynamics simulations of solar collector

#### Abstract

This thesis consists of two parts - theoretical and computational - made using com-putational fluid mechanics. The first part presents general information on solar energy, construction and division of solar collectors as well as the construction of solar systems and their applications. The theoretical part is crowned with the chapter on computational fluid mechanics, which contains, inter alia, information on the use of the k – ε model and the balance equations of momentum and energy. The second part of the work presents the results of flow factor simulation in a liquid solar collector with three different absorber piping systems (one meander system, two harp systems) using the Ansys 19.2 program. First, a preliminary analysis of calculations has been presented. It contains information on project data, dimensions of computational domains and their spatial discretization. In the next stage the results of numerical calculations have been described. That part contains information on the temperature increase of the working medium, the density of the heat flux exchanged by the tested systems, fluid velocity profiles and pressure losses in the systems. On the basis of the obtained results, geometric changes of systems and process modifications have been proposed, where some of them have been verified by recalculating numerical calculations. The second part ends with the verification and validation of numerical calculations. The main conclusion of the numerical calculations performed is the fact that the geometry of the system has a significant impact on the process of heat exchange in liquid solar collectors.
