JF - ISES Solar World Congress, Cancun, Mexico ER - TY - JOUR T1 - Steady state hydrothermal analysis of the absorber tubes used in Linear Fresnel Reflector solar thermal system JF - Solar Energy Y1 - 2013 A1 - Sudhansu S. Sahoo A1 - Suneet Singh A1 - Rangan Banerjee KW - Hydrothermal analysis AB - Linear Fresnel Reflector (LFR) solar thermal system is a promising technology in solar thermal applications. In \{LFR\} system, parallel absorber tubes (usually 8–16) are located inside a trapezoidal cavity, which receives reflected solar flux from the mirrors situated below it. The fluid (usually water) inside the tubes undergoes phase change due to the incident solar flux. The focus of this paper is to carry out hydrothermal analysis in an absorber tube of a Linear Fresnel Reflector (LFR) solar thermal system. In the present work, a generic methodology to deal with steady state hydrothermal analysis of the absorber tubes has been discussed. The single phase regions as well as the two-phase region of the absorber tube have been analyzed. A one dimensional model has been used for the analysis for both the regions. In the two-phase region analysis is carried out under the assumption that the homogeneous equilibrium model is valid. For this hydrothermal analysis, the radiative and convective heat losses from the surface of the tube to the atmosphere are obviously needed. To obtain the heat losses, the computational analysis of the heat transfer in the trapezoidal cavity is carried out. The present model can be used to predict the variation of bulk fluid temperature, variation of heat transfer coefficient, pressure loss along the length under different mass flux and different solar flux, in single phase region. Similarly, variation of dryness fraction, local boiling two phase flow coefficient, and total pressure drop can be predicted for two phase region. This model can be used to understand and design for a better \{LFR\} system.

This paper provides a transparent framework for calculating the cost of generated electricity from a concentrated solar power (CSP) plant and the internal rate of return on equity. The different factors contributing to the capital cost and generation cost of \{CSP\} technology have been discussed. The effect of variation of plant size, solar insolation and discount rate has been shown. India has launched the Jawaharlal Nehru National Solar Mission (JNNSM) and plans to install 20 GW of grid connected solar power by 2022. An analysis of the bids received in the National Thermal Power Corporation’s Vidyut Vyapar Nigam Ltd. (NVVN) bidding process, indicates that successful companies have access to low interest capital (effective discount rate ranging from 6.3–12.2%). With the current generation cost of 11–12 Rs/kW h (24–25 \{US\} Cents/kW h), an achievable target for \{CSP\} in the future is likely to be 6.5–7 Rs/kW h (14–15 \{US\} Cents/kW h). This may be possible through reductions in solar field and power block costs combined with increases in collector and overall plant efficiency.

Sahoo A1 - Suneet Singh A1 - Rangan Banerjee KW - Nusselt number correlations AB - A Computational study to investigate the heat loss due to radiation and steady laminar natural convection flow in a trapezoidal cavity having eight absorber tubes for a Linear Fresnel Reflector (LFR) solar thermal system with uniformly heated tubes and adiabatic top wall and side walls has been performed. The losses due to convection and radiation were considered from the bottom glass cover. The results are validated with experimental data. Radiative component of losses from the cavity was found to be dominant which contributes around 80–90%. Heat loss characteristics have been studied for cavities of different depths. Simulations have been carried out for various values of heat transfer coefficient based on the wind speed below the glass surface. Effect of emissivities of the tubes on the heat loss has also been simulated. Flow pattern and isotherms inside the cavity for various depths have been analyzed. Finally, the correlation between the total average Nusselt number and its influencing parameters has been obtained for the proposed cavity.
