Design and Performance Analysis of Integrated Solar Heat and Wind Power Plant | Original Article
In the recent trends in application of renewable energy sources, integrated solar chimney wind power plant has been designed with different geometrical parameter for increase the accessibility of solar and wind energy due to increasing the rate of environmental pollution and lake of non- renewable energy resources. A solar chimney wind power plant (SCWPP) is a type of solar thermal system that use the thermal energy generated by solar and convert it into the electrical energy. In the recent few years there are many researcher have exposed strongest attention for exploration the performances of solar chimney wind power plant due to its economic, environmental and huge potential application. There are different geometrical parameters and operating conditions like chimney height, collector radius, throat radius, solar radiation, wind velocity, solar absorption coefficient, solar loss coefficient, chimney shapes which are play vital role for optimize the performances of solar chimney wind power plant. In this numerical investigation a computational model of Manzanares pilot solar chimney win power plant, Spain has been created with help of commercially availableness 14.5 software. The temperature, velocity, pressure and vector distribution were plotted and evaluated for examine the influence of chimney height, collector radius, throat radius, solar radiation, solar absorption coefficient, solar loss coefficient, and collector percentage and fraction factor on the performance of solar chimney wind power plant when other parameters are constant. The obtained result is illustrated that, the power of SCWPP has enhances as increases the chimney height, collector radius, collector percentage and solar absorption coefficient but throat radius and solar loss coefficient it gives inversely effect on the power. It has been also illustrated that the throat radius gives more effect on the power of SCWPP while the effect of collector percentage on power negligible. This study is also suggested a solar chimney wind power plant at chimney height 24.4 m with collector radius 38. 92 m and throat radius 0.7m,collector absorption coefficient 0.66 and collector loss coefficient 15it gives approximately 5.4 KW power output at Indian operating conditions means ambient temperature should be 303.15 K and solar radiation is 1000W/m2. From the study it can also revealed that for further improvement in power increase the solar absorption coefficient and reduce the solar loss coefficient in same working condition.
