The comparison is made between various turbine loss models from the point of view of small, highly loaded impulse turbines operating in ORC cycles. The focus is laid on the influence of the passage and partial admission loss models and their combinations. The paper discusses the limitations...

This work presents detailed simulations of Organic Rankine Cycle processes for energy conversion of low-enthalpy geothermal resources. The working fluids considered in this analysis are zeotropic mixtures. Second law efficiency of subcritical cycles is calculated for isobutane/isopentane and...
