Abstract

In the present study, the problem of the two-dimensional steady free convection flow in solar chimney. The present model is utilized to obtain the results of the effect of parameters, which influence the performance of solar chimney. The problem investigates the streamline and isothermal inside the chimney for Rayleigh numbers ranging within (10³ ≤Ra≤10⁶), aspect ratio ranging within (0.25≤Y/X≤1) and inlet velocity (0≤Uin≤0. 5) for a fixed Prandtl number (Pr=0.7) and coefficient of arc (R=0.04). The governing equations are solved with finite-difference technique by central difference scheme. A computer program in (Matlab2012) was used to carry out the numerical solution. The results are presented in the form of streamline and isotherm plots. Also, the performance of solar chimney power plants at New Village city in Egypt is evaluated and an approximation of the quantity of the generated electrical energy is estimated.
