| Abstract | This paper focuses on the determination of the velocity and temperature distribution for water flow in a parabolic trough receiver by using simulation technique. In order to determine the velocity and temperature distribution of water flow through this receiver, the velocity of a normal and parallel direction of water flow, the relationship between the water's mass flow rate and the temperature of water while flowing trough the receiver pipe are determined. The methodology of this study is based on solving partial differential equations by using finite difference method of mass, momentum and energy conservation. This method applies a Power law model to momentum equations and applies a central difference model to energy equation. The set of discretization equations are solved simultaneously by "SIMPLE" algorithm to obtain velocity and temperature distribution within the receiver. |
