  • optimum tilt Angle and orientation for solar collectors in syria
    Energy Conversion and Management, 2009
    Co-Authors: Kamal Skeiker
    Abstract:

    One of the important parameters that affect the performance of a solar collector is its tilt Angle with the horizon. This is because of the variation of tilt Angle changes the amount of solar radiation reaching the collector Surface. A mathematical model was used for estimating the solar radiation on a tilted Surface, and to determine the optimum tilt Angle and orientation (Surface Azimuth Angle) for the solar collector in the main Syrian zones, on a daily basis, as well as for a specific period. The optimum Angle was computed by searching for the values for which the radiation on the collector Surface is a maximum for a particular day or a specific period. The results reveal that changing the tilt Angle 12 times in a year (i.e. using the monthly optimum tilt Angle) maintains approximately the total amount of solar radiation near the maximum value that is found by changing the tilt Angle daily to its optimum value. This achieves a yearly gain in solar radiation of approximately 30% more than the case of a solar collector fixed on a horizontal Surface.

  • optimum tilt Angle and orientation for solar collector in brunei darussalam

    Co-Authors: Mohd Azmi Bin Hj Mohd Yakup, A Q Malik
    Abstract:

    One of the important parameters that affects the performance of a solar collector is its tilt Angle with the horizontal. This is due to the fact that the variation of tilt Angle changes the amount of solar radiation reaching the collector Surface. A mathematical model was used for estimating the total (global) solar radiation on a tilted Surface, and to determine the optimum tilt Angle and orientation (Surface Azimuth Angle) for the solar collector in Brunei Darussalam on a daily basis, as well as for a specific period. The optimum Angle was computed by searching for the values for which the total radiation on the collector Surface is a maximum for a particular day or a specific period. The results reveal that changing the tilt Angle 12 times in a year (i.e. using the monthly-averaged optimum tilt Angle) maintains approximately the total amount of solar radiation near the maximum value that is found by changing the tilt Angle daily to its optimum value. This achieves a yearly gain in solar radiation of 5% more than the case of a solar collector fixed on a horizontal Surface.

  • Simulation and experiment on thermal performance of a micro-channel heat pipe under different evaporator temperatures and tilt Angles
    Elsevier, 2019
    Co-Authors: Li Guiqiang., Diallo, Thierno M.o.., Akhlaghi, Yousef Golizadeh., Shittu Samson., Zhao Xudong., Ma Xiaoli., Wang Yingfeng., Wang Yinfeng.
    Abstract:

    © 2019 Elsevier Ltd For a solar collector with a heat pipe, the tilt Angle is an important factor which has a direct impact on the orientation (Surface Azimuth Angle) and affects the amount of solar radiation reaching the Surface of the collector. The performance of the microchannel heat pipe (MCHP), as a highly efficient heat transfer device, can be influenced by gravity and two-phase flow pattern. The relationship between the performance of the MCHP and the tilt Angles is nonlinear. In this paper, the effect of the evaporator temperature and tilt Angle on the thermal performance of the MCHP, especially the temperature distribution along the heat pipe wall and the effective thermal conductivity, will be investigated. An experimental study with different evaporator temperatures and tilt Angles is carried out. Additionally, thermal characteristics of the MCHP have been simulated and verified by the experimental results. In addition, the temperature distribution along the MCHP and the effective thermal conductivity for different working conditions have been performed. These results would provide many references for the solar collector with MCHP system design, optimization, and installation
