Improving　energy　utilization　efficiency　and　exploiting　renewable　energy　source　have　become　more　crucial　with　the　growing　concern　on　energy　crisis　and　environmental　problem.　Organic　Rankine　cycle,　a　clean,　low-cost,　and　efficient　energy　utilization　technology,　is　eliciting　increasing　attention.　In　this　study,　the　recent　research　studies　on　organic　Rankine　cycle　configuration　modifications　integrated　with　pure　organic　fluid　are　summarized　from　the　perspectives　of　nomenclature,　configuration　modifications,　theoretical　and　numerical　methods,　and　experimental　development.　Results　reveal　that　the　nomenclature　on　the　common　organic　Rankine　cycle　configurations　is　confusing;　the　research　studies　on　organic　Rankine　cycle　configurations　are　mainly　focused　on　numerical　research　studies,　and　theoretical　and　experimental　research　studies　are　relatively　limited.　The　experimental　and　numerical　studies　are　mostly　related　to　organic　Rankine　cycle　with　a　recuperator　due　to　its　higher　thermal　and　exergy　efficiencies.　Most　experimental　research　studies　are　contributed　by　Chinese　scholars,　which　indicate　that　China　has　paid　much　attention　to　improving　the　global　environment.　More　theoretical　and　experimental　research　studies　on　other　organic　Rankine　cycle　configurations　are　urgently　needed.
