Investigations of the flow field in scaled solar chimney power plant model were carried out using a two pronged approach: Experiments for 1:30 scale Manzanares and accompanying numerical simulations. Emphasis was on investigating hydrodynamic stability developing inward radial Rayleigh-Bénard-Poiseuille under collector model. Temperature measurements provided reference data comparison with resu...

The present work involves a new and novel upgrading design to the classical solar chimney power plant (SCPP) structure. SCPP was modified by adding co-centric secondary external structure enhance energy production. In improved design, named double-chimney (SDCPP), internal chimney, operates like traditional produce electricity during daytime whereas as 10 cooling towers (CT) in series. Each CT ...

This paper expands a model different from existing models to analyze the cost and benefit of areinforced concrete solar chimney power plant (RCSCPP) built in the desert regions of Iran.Based on the model and some assumptions for values of parameters, this paper calculates totalnet present value (TNPV) and the minimum electricity price in each phase by dividing the wholeservice period into four ...

Solar chimneys are popular systems for their simple structures and clean energy generation. Thanks to its semi-permeable structure, the collector, one of system’s basic elements, transfers solar radiation system. As a result heating system air under collector by passing through it is directed high chimney in centre. During upward movement air, converts into electricity via turbine. Due large es...
