Abstract Currently electricity generation technologies by thermal energy conversions become strong demand. The objective of this paper is to present a novel
thermal study of absorber/receiver circular pipe of parabolic trough solar collector system for laminar and turbulent (k-ɛ model) fluids flow as well as
two-dimensional numerical simulation is performed using CFD ANSYS FLUENT software. Significant improvements in heat transfer and velocity
were discovered; the pattern of temperature distribution over the pipe absorber was displayed, and velocity vectors, pressure contours, and temperature
contours were studied. The impact of increasing the heat flux towards the pipe wall is discussed. Heat transfer coefficient… More >
