CHAPTER 5: Mean-line Modelling and Optimization of Organic RIT and Integration with Cycle Analysis Programme It is only for R236fa that about 29.9% and 31.7% larger Wturbine/d2 and Wturbine/d4 are achieved in (Fiaschi et al. 2012) respectively compared to the present thesis approach. Such results exhibit that, employing the RIT-ORC model integrated with the constrained GA optimization technique is very effective in obtaining high performance, compact and practically feasible ORC systems when compared to the other studies and highlights its advantages. 5.12. Summary and conclusions In this chapter a novel one-dimensional approach was proposed for modelling of organic RIT. Such approach was based on mean-line modelling with real-gas formulation and GA optimization technique to not only capture the non-ideal behaviour of the organic fluids (for reliable performance estimation) but also effectively maximize the ORC thermal efficiency based on a wide range of input variables. A screening of 12 organic fluids (both hydrocarbons and refrigerants) was performed with the above approach to identify the working fluid that provides the maximum cycle thermal efficiency considering the imposed constraints. Among the investigated fluids R245fa was selected due to its competitive performance, safety, availability and cost. Moreover, to prevent the deterioration of the turbine efficiency at high expansion ratios (typical operating conditions of ORCs), a novel transonic dual-stage organic RIT with vane-less return channel and Ma4<1 in both stages was proposed. Optimization was performed for both stages and the results will be used in the next chapter for further CFD analyses. Furthermore, to alleviate arbitrary assumption of the turbine efficiency while performing ORC analysis, three correlations (one for ηstage,ts and two for turbine size) were proposed using linear regression analysis. The correlation for turbine efficiency can reliably estimate ηstage,ts while assuring that similar ranking order of fluids will be achieved if the 214 | P a g ePDF Image | SMALL-SCALE RADIAL INFLOW TURBINE FOR WHR ORC
