Denysova T. Geometric simulation of the reflected solar energy distribution on a receiver

Dissertation is devoted to the simulation of energy distribution on the receiver of the concentrating system. This simulation is the important stage of the solar installation designing for producing hot and electricity. Reflectors as cylindrical and channel surfaces are considered in work, and also as the surfaces of rotation. The proposed method of the reflected flow density estimation for an ideal reflector allows constructing the surface of density distribution for any flat section of the reflected flow. The algorithm of energy surface description on a flat receiver is developed. The computer visualization of the point framework of the energy distribution surface on a flat receiver is obtained. The energy map with lines of equal local concentration ratio is proposed. The vector model of the reflected energy distribution for receivers as the surfaces of rotation and tubular surfaces is described. Software for construction of 3D model of energy distribution on a receiver for different concentrating systems is developed. The method of the concentrating system designing with estimation of energy distribution on a receiver and with the basis of the quasifocal curve theory is proposed.
