Abstract

The paper presents several variants of the flow paths of axial turbines with a capacity of 500 kW and 1 MW for a cogeneration plant using MDM silicone oil as a working medium. The only geometric constraint for the design of these turbines was a minimum blade height of 20 mm. The final three-dimensional calculations of all turbine stages were carried out taking into account the real properties of the working fluid based on the modified Benedict-Webb-Rubin equation of state. The gas-dynamic efficiency of the developed turbine flow paths satisfies the requirements for energy machines of this kind.

 

Keywords: ORC, flow path, spatial flow, analytical profiling method, benedict-Webb-Rubin equation with 32 members
