This paper addresses an effective method for the selection and design of optimal working fluids organic Rankine cycle (ORC) based on quantitative fluid rules, aiming to reduce complexity improve calculation efficiency model. In proposed method, critical properties given heat sources are first explored summarized relationship obtained by existing research simulations. Based concept substitution,...

A regenerative organic Rankine cycle (RORC) is modeled and optimized for the use of waste heat recovery from a prime mover (PM). Three PMs including, a diesel engine, a gas engine, and a microturbine are selected in this study. Four refrigerants including isobutane, R123, R134a, and R245fa are selected. The nominal capacity of the PM, PM operating partial load, turbine inlet pressure, condenser...

This study presents the development of a design method that has been extended to radial-inflow turbines operating in organic Rankine cycles (ORC). Both conventional and circulation available literature have reviewed. The two main limitations current make it not suitable for ORC turbine are lack real gas capability 3D blades with high stresses. Using method, flow field is decomposed into potenti...

The maritime industry will continue to see increasing regulatory requirements reduce carbon emissions from ships’ operations. Improving the energy efficiency of ships with waste heat recovery systems based on organic Rankine cycle (ORC) is an attractive way meet these tightening requirements. operational profile a ship has huge influence feasibility installing ORC onboard as it affects source d...
