This blog article is a follow up for the earlier blog “Coupled Optimization of Preliminary Design Geometry of Low Flow  Steam Turbine with Curtis Stage Layout and Rankine Cycle Parameters”, which considers more complicated case  of coupled optimization of regenerative Rankine cycle and 2 stage turbine geometry with change from partial to full admission flow.

Designing turbines for low flow Rankine Cycle for steam is challenging due to their small size, manufacturing restrictions, clearances and cost constraints. Such turbines operate at significant pressure ratios that require use of partial admission and are likely to operate in choked supersonic flow mode due to reduced stage count (controlled by cost).
