A solar receiver is designed for operation under

\r\nextremely uneven heat flux distribution, cyclic weather, and cloud

\r\ntransient cycle conditions, which can include large thermal stress and

\r\neven receiver failure. In this study, the effect of different oil velocity

\r\non convection coefficient factor and impact of wind velocity on local

\r\nNusselt number by Finite Volume Method will be analyzed. This

\r\nstudy is organized to give an overview of the numerical modeling

\r\nusing a MATLAB software, as an accurate, time efficient and

\r\neconomical way of analyzing the heat transfer trends over stationary

\r\nreceiver tube for different Reynolds number. The results reveal when

\r\noil velocity is below 0.33m\/s, the value of convection coefficient is

\r\nnegligible at low temperature. The numerical graphs indicate that

\r\nwhen oil velocity increases up to 1.2 m\/s, heat convection coefficient

\r\nincreases significantly. In fact, a reduction in oil velocity causes a

\r\nreduction in heat conduction through the glass envelope. In addition,

\r\nthe different local Nusselt number is reduced when the wind blows

\r\ntoward the concave side of the collector and it has a significant effect

\r\non heat losses reduction through the glass envelope.<\/p>\r\n","references":null,"publisher":"World Academy of Science, Engineering and Technology","index":"Open Science Index 108, 2015"}
