摘要

摘要针对太阳能上升气流塔式(SUT)电厂的流动和热力学特性，建立了3种不同的模型，并提出了最佳模型。下一步是找到涡轮吸收最大动能的位置。研究发现，与模式ii(2.4和1.34 ms−1)和模式iii(2.9和1.57 ms−1)相比，模式i内部的最大风速和平均风速分别为3.06和1.63 ms−1。ii型发动机内部最高气温更高(322 K)，湍流动能、产生的功率和综合效率均以ii型发动机为最佳。本研究结果与文献资料进行了验证，并观察到良好的匹配。

A computational approach to estimate the flow and output parameters of various solar updraft tower plants and a proposed model for the best power output

ABSTRACT Three different models were developed to examine the flow and thermodynamic characteristics of the solar updraft tower (SUT) power plant and the best model is proposed. A step is taken to find the location of the turbine to absorb maximum kinetic energy. It is found that the maximum and average air velocities inside model-I were higher (3.06 and 1.63 ms−1, respectively) compared to model–II (2.4 and 1.34 ms−1) and model-III (2.9 and 1.57 ms−1). The maximum air temperature inside the model-II was higher (322 K). Turbulent kinetic energy, power produced and overall efficiency were the best in model–II than the other two models. The present outcomes were validated with the literature data and observed a good match.

期刊介绍： Engineering and sustainable development are intrinsically linked. All capital plant and every consumable product depends on an engineering input through design, manufacture and operation, if not for the product itself then for the equipment required to process and transport the raw materials and the final product. Many aspects of sustainable development depend directly on appropriate and timely actions by engineers. Engineering is an extended process of analysis, synthesis, evaluation and execution and, therefore, it is argued that engineers must be involved from the outset of any proposal to develop sustainable solutions. Engineering embraces many disciplines and truly sustainable solutions are usually inter-disciplinary in nature.
